Firstly I am very sorry to read you feel this way, I can completely empathise with you, especially if you spent all your life savings on an investment, really not recommended at all. Everyone can admit spending your money on a project so new and not even complete, let alone has real use cases is high risk. It is always very important to get financial advice before investing a quantity of money that has such meaning to us individually; Live saving is certainly one of those.
I am obviously not here to convince you to think differently to your own experience in Cardano, however I see a lot of your grievance (apart from the delays) is around the Daedalus experience. You are not alone in your experience with the ITN Daedalus, in fact it has been mentioned a number of times that the rust code was not designed for end user experience, so getting Daedalus to perform how end users expect is difficult. Quite contradictory I know, when a testnet for the end user is being run. However, this all comes under the bracket of why the ITN introduced real ada rewards at a higher return on stake than mainnet will be, to help compensate and thank people for participating in the testnet. When frankly the work and time required for an end user has been extremely minimal. Testnet was all about human behaviours around staking with real incentives and wow, people have learnt a lot.
Not everyone has experienced issues with Daedalus, but for those who are not getting on with it, for what ever reason, there is Yoroi. You can restore a daedalus wallet on the itn yoroi for both mobile and browser extension, both extremely safe. Yoroi is an official wallet created by the Cardano entity EMURGO and has been a saviour for many users in your position.
The value of ada - Now this is a difficult one, something that traps all of us, because ultimately to buy ada at this stage is a speculation, it is not to use it right now for a real use case. That speculation doesn’t have to be for price increase, it could be to build up ada while the value is low to use for real cases when available. Either way it is a form of speculation.
Sadly and very unfortunately, ada was released when the crypto market was in a very volatile state (still is) and as such ada was dragged up to it’s ATH and dragged back down again, nothing to do with Cardano.
Since then the value of ada has been slave to the crypto market, which is not a great market to be in. Cardano doesn’t do any marketing at the moment, why would it since the product is not available to use. IOHK have been all over the world putting their feelers out and making promising connections, but this is not a hype project so they don’t come back to the community saying “look at what we potentially have”. If they did that, I wouldn’t take the business seriously and would probably have moved on by now.
Once the roadmap is at a certain stage, the marketing side will start and these connections with industries can be realised. This doesn’t mean instant success or gains in ada. It means seeing if the eco system will be successful or not. In turn that either brings more value over time or not.
I do not personally like crypto, it has a bad name for itself, plus full of copy and paste projects making big claims with software that will never achieve. I am literally only interested in Cardano and only hold ada.
Cardano is different, they are far more professional and although your user experience hasn’t been great at all, they are creating their blockchain themselves, everything is new built from the bottom up. The current code (rust) used for the ITN is not the code that will be used for main net - completely different. Haskell is designed for end user experience. Up to you if you want to wait that bit longer to see if there is a difference when we move over to the haskell testnet (iminitely).
Cardano may be a few years old now, but it’s not a complete company or setup, it is very much in its building not ready for ‘clients’ or massive amounts of people to develop on and use the blockchain. Only you can decide if you are lucky enough to discover it so early on or not. Most will say not, until the value of ada goes up because that’s all they’re interested in. I’m not saying you’re one… but anyone who just gambles with their money without real research or understanding is far more likely to lose all their money. Cardano is a great example, like you said - has been declining in value year after year… if i gambled on ada, without true understanding I would of also left at a loss now. Especially if I watched and listened to random people on youtube and third party written ‘news’ articles from people who barely know facts themselves.
Good luck with your future endeavours what ever you decide. Nothing is guaranteed in life.
A harsh world where no one owes us anything and unless we win a lottery, get rich schemes do not exist. Time will tell if Cardano is a great investment… but that doesn’t mean in two, three years since release. It can take many years, look at every successful business. I hate comparing bitcoin and cardano, but even bitcoin is 12 years old, took nearly 10 years to gain the value it has today. Cardano certainly isn’t going to increase in value for just being another crypto currency, there are plenty of those. Cardano needs to be the third generation and give something more. That is what cardano is working towards, it’s not ready yet
