Full time trading with crypto can be HARD! However, a lot of new traders fail due to two fundamental flaws.
1 - Not utilizing discounted trading platforms or functions
2 - Not utilizing stop losses (or setting stop losses in the wrong spots)
Determining where Bitcoin will go hasn't been hard. Determining where Bitcoin will go from a neutral market...now that's a different animal. If you're bullish on a certain crypto always use a stop loss. Look for points of resistance and support, then set your stop losses accordingly. If you are trading and "scalping" your trades, you need to make sure you are paying little to no trading fees. Coinbase pro allows "makers" to pay $0 in fees (limit buy and sell orders).
