There are a lot of factors that should be considering in order to lessen the risks in trading. First we must identify first what type of trader are we, are we passive trader or are we a active trader? By identifying that, we can knownwhat type of strategy that is applicable to use. Strategies of long term and short tern trader are not the same so it is better if we will know what type of trader are we
It mostly works the other way around
We can identify our stance (long or short term) based on actual strategies and approaches we use. This is what counts in the end, while the specific type of trader that we drift to is of no particular importance. We can be actively trading one coin in the short term, while passively holding another for the long term
Diversification is also matter and be sure that do not invest all of your money in just 1 coin
Diversification is meaningless with crypto. If you want to reduce risks (as this is what diversification essentially comes down to), simply buy Bitcoin and forget about altcoins
