When you make profits in this market, I am very happy for you, but I personally think that although altcoins are risky, I have to say that a good altcoin has a good timing and higher profits, which is very exciting. It's also risky.
How possible is it to find that "good altcoin with a good timing", i'm afraid it is a white goose chase and too risky, some altcoins are good at pumping if you have the crystal balls to guess the correct time it will, but you must also have crystal balls to sell it before it starts dumping, altcoins is a tricky and risky 'business', there isn't even an altcoin that can be considered 'good', a good altcoin is one that is currently pumping in the market, once it can't pump, another one that is pumping becomes the latest good one. If you want to buy a decent coin that is useful and surety of profits in the long term, then buy BTC
