2% was only an assumption to make the calculations, still dont know which risk would fit in my trend strategy yet.
Is not for diversifiying towards crypto coins, basically is for diversifying my strategy in different trades adjusted by volatility.
Is better having a portfolio management skill rather than enter and exit strategies.
It's my opinion that unless trading with a huge amount you don't really need to diversify too much if you're day trading. There's little wrong with going all-in as long as you have a strong stop-loss strategy that you follow at all costs.
