This is a very subjective opinion. If you are trying to make quick money, then memcoins theoretically provide such an opportunity. I won’t say that the ratio of successful memcoin projects is approximately 1:5, IMHO. You can simply find yourself in a situation - and if we are talking about memcoins and other shitcoins on Solana, then it is almost guaranteed - when you buy this dubious coin after seeing a “green rocket”, and then only a quick fall to 0. Altcoins are different in nature, they were created either as digital shares (tokens), or as a means of payment/incentive within the project, or generally represent the native currency of the chain. I would never compare them in any context.
