I agree about trading. Also all the news is totally random.
The only person i know who invested successfully was holding long term index and optimizing leverage.
He ran a lot of Matlab calcs on the S&p and NASDAQ and found that historically it's worth it to buy and hold indefinitely up to 2X levered Nasdaq and up to 3X levered S&P.
Ive been trying to convince him that Bitcoin is an index with enough historical data to be comfortable with.
