Coins, such as ethereum and bitcoins, are better kept, of course, but there are many other altcoins that even make fifty percent growth now; you can trade these coins even at this time.
Yes, it really is, but such situations are very rare and in most cases those tokens and coins about which you speak simply cannot predict their growth. That is, it turns out randomly. I do not understand how to analyze projects in this way.
As you look at the market there's no sign of bull run so the good thing is we are able to becoming a holder but if the perfect time will come then they are able to sell those coins and wait for hype again.
