It might be safer to buy a more solid coin, especially if you think the returns can come back faster than the natural growth of the coin. This is an advanced form of arbitrage, esp in such a volatile market like the crypto market.
During a bearish market is the best time to buy into coins and tokens. Just make sure that the coin or token you are investing into has a good foundation, qualified team (to implement what the coin actually promises to provide) and solid tech.
in my opinion, since today the cryptocurrency market is still at the development stage, in order to meet all the needs of cryptocurrency users, it is necessary to develop exchangers and cryptocurrency exchanges in the Scope. Thus, I believe that ico companies developing new trading platforms are very promising.
