For me AVAX (avalanche) Is the coin i got good profit in this coin by investing 5 times.
At that time, I got CTSI. But, after the crash, I stop doing it because the market is very unstable at that time. Although the profits are not kind of big profits, at least, I could repeat earning profits from investing and trading CTSI at that time. This was one of the popular altcoins at that time. But now, this seems like silencing.
Actually, continuous n earning from investment is profitable, moreover if we have funded a certain altcoin with the results. However, we also know that market will be changing again and we may also change our strategy and coins for investment or trading.
Next to Bitcoin, it was Ethereum which has given me a good profit multiple times.
This is one of the must-have cryptocurrency besides Bitcoin. This has been a longer time and keeps developing following Bitcoin. We also know how the trust Ethereum. Probably if I can expect more, BNB may be one of the other profitable investment to have. I really expect that the path will also follow Ethereum that were able to skyrocket highly in the last bullish era.
