I doubt that EarnOnVictor or the other guys promoting trading are doing as great when the BTC price goes into breaking upward periods, like it seems to be doing now, since they cannot really get the ups and downs correct, and then when the BTC price goes up, they are caught outside of their trade and with fewer bitcoin than they should have had.
Trading is easy in theory, demo and on paper but in practice, it's hard or let's say super hard to get two things done: protect trading capital, get profit from trading. None of these two things are easy to done with good results for traders. Most of traders fail in both things, it means they don't get profit and lose their original trading capital too.
Trading requires very active actions in the market and it's overwhelming with many people while investment, for example, with DCA strategy, requires less active actions, and somewhat let's say investment brings passive income with less required activities in the live market.
