So start out small and work your way up.
What is your opinion?
Sell everything and invest in projects you believe in.
I asked my relative who did a lot of
bad things to me and our family as a whole to do exactly this - sell our flat that was vacant [we were living overseas] and invest 1/4 money in BTC, XMR, ETH and some shitcoin. Of course their answer was
NO. Now we have nothing, no, sorry, we have our flat - we are living in conditions equal or worse than homeless shelters offer

.
You know it's also hard to sell everything and make all in to cryptos since it's volatile, and you can't blame your family for not doing so as they didn't know what exactly is this. It's better if you suggest to put a small business so it can add up to your daily income.
Don't fully depend on cryptos, do some real job.
