true that's why divide ur funds into 50:50, put the 1st 50 into the market and try & adjust &if lost, short/long it as per ur situation..but whatever u said is true.
i spot trade, up works and down works, you lose nothing, the value of the crypto might go down but you still own it and can wait however long it takes for it to go up again. Try to sell before it drops and rebuy with everything you have at a lower price.
Then go to the opposite. I made profit doing opposite what I analyze, because most of the time, analysis is wrong. Once profit is enough, close the deal. Dont be greedy
