Its nice to quiting trading when you got some profit and it is not that bad if you are going to quit trading because you can make another investment.
But now Bitcoin price is growing up since you start trading, you can use your 40BTC for anything man. Buy a car maybe lol. Good Luck out there.
but i think it is not good to quit trading if you are just doing so because you lost money in trading. i think if you have lost some money in trading you do not need to quit trading, but you need to change your trading strategy and planning and hope that next time you will not lose money in trading.
