i think no,now the market is very good the end 2017,now we can buy eth,btc,it is safer than altcoin and hold for the end year or next year,i beleive market will grow up
Yes market now is increasing more and more but still it is not very late, bitcoin right now is at increasing mode so if you will buy right now and will hold with patience for long time then you will earn high amount of profit, I use bitcoin as currency and at the same time I try to buy more bitcoin because it is getting expensive so it is an opportunity for all of us to store bitcoin as much as we can store for long time. Gradually market is turning green so buy now as much as you can buy, it can never be too late because bitcoin has fluctuating nature.
