If any body take 10% entry then I think it's good but we should hold also some stable coin for crash. Falling some 50% from the top is not a crash in cryptos...It's just a correction...wil consider it crash once these cryptos fall 90% or so....like BTC falling to 7K....this will be a good time to buy
Fall or correction, depending on the last buy price a trader can decide on whether to buy or not. A single coin can crash but it does not need the entire market to crash per se, but usually they all follow suit specially if the starting was with bitcoin.
Fall of the market is the best time to buy tokens of new and prospective projects.
That is why it is necessary to constantly monitor the market to find the best projects for invesment that it will be to bring profit in the future.
If you do that you will find out that 99% of projects are failures from the start. Because they lack intrinsic market making capability and they compete against a hugely funded mainstream market which is doing a similar thing previously.
So if you want to profit, buy form the top 5 coins mostly bitcoin and sell during the bull market. No use spending time on doing so much research, altcoins are never going to be as big as bitcoin is.
