Everyone has their own expertise. Some are good at reading and doing research on projects probably for ICOs, some are good at day trading, some are good at long term trades, etc. Research on all of them. Choose the one that best fits your current knowledge and what you prefer doing.
This really helps a lot! I have a last question though. Personally what do you prefer between trading and investing?
I personally do both. But the trading I do isn't like what people usually do(day trading). I personally only make trades like every week or so. I find day trading very tiring and my sleep has been affected negatively. Which one should you go with? Try out day trading in like maybe a day or two. If you found success with it and if you somewhat enjoy it, then probably go with it. Just make sure to not go all in with your trades. Only risk like probably less than 5% of your bank roll at every trade since you're just starting out.
