Nothing is static with the cryptocurrency market just like the other markets that are tradable. Everything changes and we should not expect exact thing that happens previously to happen again because of the way the market is programme and move which makes it difficult for us to easily predict the market.
Crypto strategy is something we need to to be readjusting everything we enter the market to trade because it is very hard for the market to move in the same pattern and for things to work in the same way we want it to move. Strategy cam work well with the current condition of the market and changes later because of of different market factors that might have created momentum.
Right as cryptos are more unstable than the other but for your second sentence, I think that will depend on the coins that you pick as some coins can repeat their history while the others don't have that kind of ability like once they dump, they will stay on that level forever.
The market is programmed to be unpredictable, I think that makes sense because if it works the other way around then no one will ever lose. If we are trading, changing and implementing new starts might be better because like we said earlier, cryptos are too unstable so the market can change from time to time but when it comes to investing, I think we can just recycle our old strategies.
