Yes 2017 was the best year of crypto but i think we will see more exciting time in the future. That was the best but it doesnt mean that is the best and last.  Surely 2017 is the best but i think in the future we can see too many years like 2017. Only we need to wait to see these times.  Too many people earned huge amount of money in 2017 and now they are selling . They will start to buy back in near future.
