Technically it is still a possibility even though the price is already at the overbought level. As far as I know, during the cryptocurrency world, the biggest influence on the rise and fall of prices apart from technical analysis is fundamentals. Fundamentals have a strong influence on cryptocurrency price movements. Just pay attention that Bitcoin with its fundamentals is able to continue to maintain its current price and is still able to continue its increase, even though Bitcoin technical analysis predicts a lot of declines. Don't be too confident about it, altcoin movements are influenced by Bitcoin and Bitcoin's dominance, as well as fundamental factors of the altcoin itself. If you are careless in collecting data, the losses experienced will be greater, cryptocurrency is not enough for what you say.
Mostly we have seen the coins prices have a change due to the bitcoin changes, as we can say it is bitcoin fundamentals or what we have to say it? Typically when the price of bitcoin is moving up, as a result the whole market turns into green as we can also say most of thr market turns into green. But when we see some bad news or we see some changes in the bitcoin price the market turns to the red side and mostly people got into loss there.
In this place also some traders got too early their exit but most of the trader didn't have much time to recover themselves so they turned into the loss. So bitcoin fundamentals plays an important role as well.
The key is Bitcoin, Bitcoin experiences an increase and then sideways altcoins will rise like crazy. If Bitcoin does not experience a sharp decline like yesterday's bearish period, altcoins will continue to rise even though they are already at overbough levels.
I can say that crypto trading is simple, you understand the Bitcoin cycle, you will understand the Altcoin cycle. Just position yourself with technical analysis, it is very likely that trading will make a profit, but I don't guarantee that trading will be successful because everyone's targets and analysis are also different.
