if only to spread about bitcoin I do not think it's hard, because just show me my income to them while joining this bitcoin. the hard part is to understand the bitcoin.
It will all be just envy which is left for those who didn't listen.
Same with my friends who are now asking how I do it.
I gave them the details before but they didnt listen just because it is still at small value.
But now, with this large price I am profiting a lot and they can see it. All they have is regret to not pursue what I have given them before .
