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.
Yes, last year had a great fluctuation in price in where we can earn good profits. It was started in october 2017 until the end of year of bull run but now there's no specific time when to fluctuates but I believe still it can have potential to surpass in it's current price in the end of year.
