There are so many altcoins that will do 20x or more between now and this time next year and I just feel as long as I find 2 or 3 of them then I will be fine.
Yes there are plenty of altcoins that will do it but
all most of them are premined so the owners have full control over the price and you won't have any chance to escape if you keep your attitude.
While the greed will be eating you and your brain will be full of dopamine from this great feeling of becoming rich, this scammers will dump it all.
There is not particular time we are expecting to sell our altcoins but the best time for us to sell without being greedy is when we are already in profits. Altcoins can move very fast and the same applies to falling, so we have to be prepared and know what we are doing so that we don't have to finally lose trying to hold when the market is not in our favour. Making money is what we should be after but we don't have to be greedy because this is one of the factors that can make us lose more in the market. I am always prepared to sell anytime when I think price price might fall anytime which could make my profit end up becoming loses.
