"Trading is only a matter of patience. LOL." - LOL?

I would not recommend listening to that for successful trading. Patience is an important matter in real trading, yes. But in Altcoin trading, it is pure luck. The reason behind that is simple: Altcoins have such a low volume that your profit solely depends on single individuals, and if they're willing to move the coin into your direction.

Buying and selling Altcoins really has nothing to do with trading. It's gambling. And if you want to make money long term, I'd recommend using markets which have real volume, because then, you can spot trends and use them to profit.
So, recommended markets are generally LTC and upward (meaning in crypto, only BTC, plus traditional markets, such as Forex, Commodities, Stocks, Indices). It's also gambling to some extent, but you're not depending on where a small group of often crooked individuals want the market to move.

It takes time. Many traders take years until they become profitable traders who manage to scoop consistent money off of the markets.
If you want to keep (and maybe increase) your money, I'd recommend to stay away from Altcoins completely.


.edit: I lost thousands trading Altcoins, when I was "young" (in crypto experience terms). Did not have the experience I have now, and I misunderstood classic "stay the fuck away" signals (ongoing pumps) as "fomo in ASAP" signals. Glad it was no money I was depending on in any way.
