I was just reading a report about BTC , A USA family sell all there assets and with that amount they invest in Bitcoin in 2019. as in 2021 BTC was on its peak ! So they get huge profit.

But as a dump then came in crypto market, for every investor it was really a great shock.

What you people say about this topic ?
Should we invest just like them or should start with a less amount ?

as Bitcoin came down in past months . it can be a great loss for those who invest madly !

Must drop your suggestion !
