One important thing in trading don't be hurry up entry position to buy or sell, always looking how potential price of altcoin or bitcoin you want to invest have reaches most higher price or not.
If you are a trader, and you are desperate to buy a coin, then you might end up buying when the coin is still at the top, always take your time to study the market before entering, trading is different from investment, when trading you have to be really careful with your analysis, but if you are holding for a long time, then it doesn’t requires much analysis compare to if you are a trader.
I am so sad heard with your loss around $40 depend your capital $100 but which one you trade in future or spot trading?
I had some crazy experience with future trading when I started trading, since then I already made up my mind that I won’t be trading future anymore, so I hardly trade on future, and whenever I want to trade, I always do it with just little amount of money. If you are new to crypto, make sure you avoid future trading, just focus on spot trading first, when you understand stop, then you can start giving future trading trial with just little amount of money.
Use stop loss when your capital decreasing above 10% to minimalize with your more loss in trading
Not everyone is always advising the use of stop loss, I don’t really use stop loss because am always online to monitor my trade, but I do recommend newbies to make use of stop loss, because they don’t have much experience yet, and it’s going to help them reduce their loss when they are in a trading.
