Nice reflecting about our mistakes.
I remember when I began to trade cryptos, as less than 5 USD left me to buy some coins sometimes I use to expend a lot of time reviewing each; once I remember to count more than 20 coins (in the bonanza of 2017). I used to finish really tired after take a look at 20 charts! Now I am doing exactly what you mention, no more than 4 coins, and mostly in Investment with Rewards. It allows me to make a faster move if I see it necessary.
