It's very stressful to see red percentages in the market, but that's normal; the simple explanation is market volatility, and if you look at the past charts, it'll still recover. You must have faith in the asset in which you have invested; have faith in BTC; he will grow as he deserves.
That's why I've came to the conclusion that I have to risk it and invest more heavily into alt coins. In the hopes doge pumps again. next time if it gets to just 50 cents I'll sell half and convert to bitcoin maybe. same with the others. I mostly am just holding ADA, KSM, XMR, VET. If they can pump up at higher percentages, maybe, I can keep up with the average investor maybe.
Actually, mate, you're on the right track with crypto investments, and you don't need to be concerned about how long it will take to make a profit because the coins you've mentioned have potential. I've done some research, particularly in ADA, and I believe ADA is simply waiting for the BTC price increase to do the same.
