I was thinking alot about safety and having big money in crypto only in cold wallet is not enought or
in crypto eschage wallet.
Does it possible to have copies? for example I have 1 btc in exchange and I copy that btc to cold wallet,
it does not mean I have 2 btc, I have same 1 btc, just I have copy or so called backup, this is like a files backups we are using to storage. I have btc one like original in exchange, but if I lost it because of hack, I can restore that btc from the code in cold wallet
It would very big improvment for safety. Having 10millions in cold wallet is very unsafe, also the cold wallet can be damanged and so, having only in echange also many hacks problems and so.
