If you have enough Bitcoin than your are good on your own and you made good fortune. I will say you have to invest in real estate business aor big business so that you should generate passive income.
Me I will prefer to stay off, given someone financial advice on where to invest and where not to invest. If he has been able to gather up that bitcoin, he should have plans for himself. The more perfect advice I can give to such a person in this state now is how to secure that wealth and how to remain anonymous and not parade it online and attract attention to himself.
