This is just another thread about regretting that someone didn't buy Bitcoin when it was only worth a few hundred dollars, but what is the use of it when time cannot be turned back. Even if you had invested then, can you say with certainty that you wouldn't have sold 2 or 4 years later and that today you wouldn't still be furious that you did it?

You say "invest now?", but what about those who have no money, or who do not understand what they are investing in?
