For me, you learn best through experience, if you don't want to take risk first since (if) you're a newbie , you can use a trading simulator.
it will be easier if we start with a lot of capital because we can spread our investment to many types of coin crypto and in a very uncertain market situation, we better save our money first and do not spend coins first. because we have not been able to see market trends that show a stable sign
I do not think this is good. When you invest in many coin altcoin, you must monitor and analyze the price of many coins. This scatters your monitoring and analysis. So I see not good.
