It is best to start your investment in Bitcoin and top coins to reduce risk. Other less known small coins can go out of business in a bad bear market like this or may not recover back to highs.
I think that the correction of the cryptocurrency market is taking place today. And most projects that do not have a final product or are not interested in society in their idea will leave the cryptocurrency market.
I believe that right now, I does not matter what coin in at the top. The collapse had been huge and this is the time when everybody is leaving the market except the habitants who have positive vibes for the recovery.
