Very hard to predict the future, but to start trading when all crypto dumped more than 80% will be good times because the price has potential to going up because the price oversold. We have to use stop loss in trading because level support can be resistance, the price of crypto really unpredictable so we have to create better management of risk.
Of course, the risk that you can fail is still very high. However, it is really the truth - the prices of the cryptocurrencies fell a lot. Now, the time of the bull run will come, and the tokens will go up.
Before stat trading you need to learn something like that you had enough money to invest and you have enough time to manage your trading business to the higher level otherwise the money that you are invested definitely last and the time will be definitely waste so think and make decisions.
