these are all talk and none of them would help any beginner to learn how to become a successful trader. in my experience people have to start trading to actually learning things. if you are trading Forex,... there are always demo accounts you can use to not even use your real money! and in cryptocurrencies you can always start with a very small amount of money and don't risk anything big.
I think it's truly reasonable to state that at first it is important not to spend a lot of money, just to spend time on experiments to see what's going good and where one has some problems. On this market the prices change all the time, but I bet there isn't much use in selling something with less than at least 10% profit, so I guess constant buying and selling doesn't make much sense.
It is also a lot easier to simply invest money long-term and not waste time to daily trading, but there's no regular profit in this case.
I've never tried daily trading, only long-term and short-term investments, because trading requires spending quite some time regularly. I think it's worth trying some time later when there's a certain daily amount of time to spend of that.
I would say that daily trading is probably one of the hardest to become successful at. Most of my most profitable trades had a holding period of 2 weeks to 2 months. But I think one of the most helpful things is actually committing a little bit of money and trying things out.
You do have to be careful picking the platform you trade on. Some of the exchanges have a lot more issues. For example, I was trading some crapcoins on coinsmarkets when they pulled an exit scam. Or an exchange I've steered away from is Yobit, I've heard and seen lots of complaints that they won't update wallets and will be on the wrong chain for lots of coins.
Ultimately, short-term trading has a lot of the same mindsets as long-term trading, you're just taking profits earlier and trying to bump up the compounding effect. You're looking for coins with real potential, not coins that fall in the "yet another clone" camp. Also make sure you don't get caught in coins with very low trading volume, or you can wind up thinking you've doubled your money, but find out that your sell orders aren't filling.
