Scalping is really hard and I see it was not a profitable strategy in a volatile coin like BTC. I see a lot of market analysis, in fact, I have mine but most of the time I fail to be on perfect timing, and usually, I lose. If we only use Bitcoin for trading, scalping is not good but I see it was effective for altcoins where whales have so much participation.
Scalping can be done when we have a lot of time to spend on the computer but for those who have limited time, short-term trading could be the best choice. Both of them are profitable (or even not) as it will depend on the traders.
Scalping is "too" hard, I mean sure there are some people who know how to do it, but if you ask me it's near impossible for me to do it. I tried it a few times before and I failed and I have been trading for years now, so that means any newbie out there would have absolutely no chance at all, would not make any logic to do it.
I rather have a situation where it would be smarter to end up with a profit in the long run with holding, or regular spot trading because those are not that difficult to follow up, and would give you an easy way to make profit instead of this insane method called scalping. Even with a lot of time, it's very hard to do, requires you to be 100% focused at all times with no margin for error.
