It is better not to get along with its wave especially if you cannot take the risk. Might be better to wait for your chance to enter on the crypto you are planning to buy. Or you can just buy the crypto you want then hold it.
So far, I also think holding back is the best decision for altcoins right now. However, things are pretty bad out there. even ethereum-class coins are not growing very fast. So far, I am still holding on to altcoins, because I believe that after bitcoin season, altcoin season will arrive. Well, that's not a very strong speculation, but I decided to hold back rather than exchange bitcoins.
