Rule number 1 for trading Crypto. Whenever a random dude comes up saying he has the perfect coin that everyone is absolutely missing out, SELL EVERYTHING YOU HAVE AND BUY IT RIGHT AWAY! Dude obviously knows better, otherwise he wouldn't be talking about his coin online with other people, who would risk other people's money like that?
Also, if that person mentions ETH has more upside than BTC, do everything x100, because my friend, you have just discovered a gold mongering leprechaun who wants nothing more than to make you rich. Don't slack, buy that sh!t now!
