3x-5x is difficult unless the BTC moves upwards, but luckily, the majority has an expectation of an increase related to next year and will not be ineffective. If this increase is over $15k and these altcoins show some effort themselves, we may see 3x. I do not have an idea of most of these altcoins, but if they are worth enough to wait, I suggest you wait.
