Also you shouldn't be disappointed or give up in bitcoin or crypto investment if trading hasn't work for you just try to HODL bitcoin or at least do more proper research on the altcoin you choose to HODL while if you are still have desire to trade, reduce the amount you use in trading, try to avoid risk when necessary and continue to learn to improve your skills and knowledge about trading.
I have a mentor who once told me trading cryptocurrency is trash and isn't worth the effort but then people fail to understand probably because they have seen a few who traded cryptocurrency and made some good money from it hence it becomes a point for them to believe that trading is actually a way of milking the crypto market until they suffer huge losses as this then they will accept the fact that hodling is better.
Time factor is the only separating difference between a crypto trader and one who is hodling, these two persons ends up in good profit but this have relativity to the and their capital but Hodling is way safer and profitable so just HODL
