there are some factors that you need to pay attention to when investing in the crypto currency: it is, firstly, a suitable investment object, be it equipment for mining, trading on the exchange or an ICO project. secondly, the size of the investment is important: since the crypto currency is a high-risk instrument, invest only free money that it is not a pity to lose. if you have a small budget, I recommend that you invest in promising and cheap altcoins, or try your hand at cloud mining. further - you need to conduct a thorough analysis of the market, without it you do not have the sense to invest money.
