I have day traded in the past, and quickly discovered I'm not actually very good at it. I've had more success with swing trading, but I find the time involved doesnt really make it worth it, and tbh, I cant really be bothered.
90+% of day traders lose money in their first year, so unless you are particularly skilled in technical analysis the prospects arent good.
Most serious day traders use bots (like hummingbot) to impliment their strategy rather than doing them by hand, as the crypto market moves very very fast.
If I were you I would start with swing trading (ie buy at one price, then set a limit sell order for a substantially higher price, as soon as it sells, set a limit order to buy for a lower price....then if and when the market runs away from you, reassess.
In terms of things to consider.
- if you are day trading on only one exchange you will get rekt. Arbitrage is a massive part of crypto trading, and most amateur traders will have 3-4 exchange accounts. Pro-traders will have around 8-10 Swing trading is possible tho.
- Watch out for fees. Typical fees are around 0.1% for a taker and higher for a maker.. Usually around 0.2%. There are also withdrawal and sometimes deposit fees if you want move your crypto off the exchange.
- Not your keys, not your coins applies. You do not have control over your private key while it is on the exchange, so if there is an exit scam or the exchange gets shut down by regulators, you have lost it all. Crypto is not FCA protected, you are your own bank.
- Crypto-crypto trades and crypto-fiat trades are taxable under CGT, whcih is an added complication and HMRC are becoming more proactive in tracking crypto. Its possible to end up owing more in tax than you actually have left at the end of a tax year.
For a new trader, I'd investigate stop-losses to minimise the impact of market crashes (crypto markets are both highly volatile and highly irrational), and stay away from margin trading, no matter how tempting it may be.
