well, the most important is to be reasonable.... so, be patient, watch the market's fluctuations and then decide to buy more or not. Another important thing is to "never invest more than you cannot afford to lose", remember that quote. If you want to do something, different from buying btc, but still very connected with cryptocurrency industry, I recommend you to take part in a cryptocurrency affiliate program. Almost every cryptocurrency exchange has its own affiliate program. I recommend you to check for example this CoinDeal's one, I've used it and it's pretty profitable.
