Crypto trading is getting more and more technical as the days goy, and the formula that worked back then in 2018 is no longer accurate at this moment 2021 came with a lot of upgrades with many exchanges coming up with new features on the exchange.
So being forced to ask what are the most updated guide for newbies that have been out of trading for some time now.
The volatility has gone down a little bit but if you had a good strategy before then there is no reason to think such a strategy is not going to keep working, now if your strategy was just to invest in an altcoin and hope that it did a 100x movement out of nowhere as many people did during the 2017 bull run then you may have a point, as this is way more difficult to achieve in this day and age, but even then such a thing was not something that you could do on command so I do not think anyone could have used that strategy to get sustained success.
