It is theoretically a good moment to invest some money in BTC?

Hi.
I'm really a newbie. I have invested about € 500 when the BTC was in 6000USD. I have maintained my position despite the rebounds on Sunday. The profit that my Coinbase presents right now is around € 15. I do not know what to do. Can you guide me please? Thank you.

What Alts do you think may be likely to have the most important rebounds? Historically which ones have been most affected positively by these rebounds?
