What do we have to trust crytop that is if a decentralized non-custodial currency at where the investors stays anonymous and the P2P transacting merchandises too tends to stay anonymous couple with the fact that frauded transactions could be untraceable and any transactions mistakes such as mistakenly sending to another wallet would be unrevisable and yet individuals stores their their assets and not just funds in there so comfortably without panics but they don't rely their trust with the traditional fiats where there is an existing financial regulatory authorities whom would tend to give you a financial security assurance?
First off this is written like total crap or shit or garbage.
Basically as I understand it you ask "how or why do we trust crypto when it has shown us to be filled with theft"
Answer is good crypto is trustless. You do not trust it.
This means you do your own research and find at least 2 offline wallets for your coins.
It means you have at least 2 online wallets for coins.
IT MEANS YOU HAVE AT LEAST 2 EXCHANGES FOR COINS.
Once you have the six things above it means you must understand that only the offline wallets are safe.
simple method
10 units of wealth in offline wallet 1
10 units of wealth in offline wallet 2
1 unit of wealth in online wallet 1
1 unit of wealth in online wallet 2
1 unit of wealth in exchange 1
1 unit of wealth in exchange 2
this is pretty much the way to use crypto correctly.
