t all depends on what youre in to. Some may attempt to capitalize on ICOs just as they would a company thats about to go public. Heres an example of one that looks promising.
Others may choose to invest in major coins that have been around a while (BTC, ETH, LTC, etc.). Then, there is also the opportunity for buying mining contracts which have more steady, albeit very modest returns over time. Because of how mining contracts work, they are typically safer for the amateur investor because they payout consistent returns independent of the volatility in the market.
Another thing to consider is actually trading, or investing - if youre going to trade, you better do some research and not let your emotions get the best of you, some even consider using algo systems for the same reasons that they buy mining contracts. However, if you are not interested in speculating/trading then you can just buy and hold which is perfectly fine as well. Hope this helps, upvote if so
