New in the crypto world

Good evening,

I am new to cryptocurrency and I have few question to cardano.

I downloaded the daedelus wallet and let it update to 100%.

I lost often the connection to the wallet. Is this normal?

I thought the wallet is offline?

Is this a online Wallet?

I have now 0 ADA on this wallet and i maked a paper wallet. I see on these Paper wallet over the QR Code a big number of letter and number combination. If I now buy ADA from a exchange do I have to give this number to the exchange and they send me my ADA to this address?

If they sending the ADA coins to this address, did the coins now stored on my paper wallet?

Why the big number on the paper wallet is not the same as these number direct in my daedelus wallet? And why I can every time generate a new number? How Cardano know that all these address goes to my wallet?

Can I buy ADA direct from the developer of cardano?

If I delete the wallet and restore the wallet on a other pc again, did I get all my ADA coins back?

Is it true that 95% from ADA goes to a japan investor?

What will be the full amount of ADA coins for the next years? As an example if u double the coin the marketprice will drop by half.

brest regards
