Honestly bitcoin is the best thing to invest in at the moment. It's quite low and stable at the moment, and it's only a matter of time before there's newfound interest.
For me bitcoin is first and best choice investment for long time (more than 5 years). Besides bitcoin i also save some altcoin like etherium, monero, dash and doge. The precentage is 70% for bitcoin and 30% for altcoin.
Bitcoin is very good investment if you have patience to wait for its upward thrends but also it's so dangerous if the price suddenly go down for such certain instance and if you invest on this coin surely you need to monitor the price since bitcoin is not stable and the movement of it is so fast that we can't imagine, but i don't invest on bitcoin for now since i am not sure for his movements at this moment,
ICO's is better to invest with but we should select those devs who have great vision and many project development for his coin.
