For your third question, nop, scalping is not worth it. I currently make almost 100% per month because every time, you have a couple of cryptos that pump way more than others. my job is to find those currencies and trade them. However, scalping in crypto is too risky. one week, you make 20% and the other week, you lose 30%. there are a lot of immature traders in crypto and this has made it so darn hard to scalp long-term. I'd suggest you look at the medium-term picture and not scalp. the future market will reward you for that.
