I have tried scalping on BTC/USD pair as one of my friend suggested it for scalping as this pair has more volume but for same level of capital with holding, I made more profits. So, you may stop recommending for scalping. It is not a way to trade cryptos.
I also have tried almost all the methods of trading under the sun and I can tell you that I have failed all of them, every single one of them. Right now, the only thing I have managed so far without any problem is buying long term and keep buying and buying to increase my bitcoin number, that way I can actually increase my bitcoins but also if there are any falls I am taking advantage of that as well.
Whenever there is a fall, that means cheaper bitcoin for me, if it goes up I still buy anyway because I believe the price will constantly go up and up and never go down in the long term, so if I purchase today and it drops, I know in a month it will recover and make me profit.
