I find that buying a lot of Altcoins in 2019 is a wise decision when the market is getting better. The price of Altcoins is still very cheap to invest and you can make a big profit in the next few months.
Yes, you are right, if we are talking about quick and small profits, then yes, there is growth, but investing in everything is fraught with risks, carefully choose coins, keep the main ETH, BTC, USDT in the ratio (30/30/30) and only a small part (10%) of the risk on coins with a small trading volume, or a small value.
