This time last year, bitcoin was still around $1000+ and nobody could think or imagined bitcoin is going to rise from 1000$+ to like $18000+. There was a huge market rise of it when closing July, August up till December
Bitcoin price last year 2017 obviously is much better than the price this year 2018, but for the new investor now is their time to buy a volume of bitcoin because we do not know when is the time the price going up, imagine 6,000 USD price now let say you can buy 1 BITCOIN then after the few months the price is gradually higher then it will raised up to 18,000 USD like the price last year? that's nice right.
