when you do trading, do you always think about this, "buy some, sell some, hold some."
I don't understand your strategy that buy some,sell some and hold some.Are you talking ablut bounty rewards?
You really need to follow biy low and sell high if you want the profits.
no, im talking about trading, for example i buy 100%, sell 70% and hold the 30%, for me its increasing profit.
it can work and it is a valid strategy but the final profit depends on what you are trading. for example if you are trading some useless shitcoin and bag holding 30% of it then your final result will be a big loss as that shitcoin gets dumped eventually because it is inevitable in pump and dump altcoins.
but if you are doing it with something good like bitcoin then it can be a good strategy.
for example you buy $1000 worth of BTC then after it went up you sell but you don't sell all of it. instead if your total value is $1050 you sell $1025 of it and keep $25 profit in BTC and $25 profit in fiat.
