If you are already here last 2017, im sure its obvious that its is now the right time to buy crypto. Cheaper price will lead to higher income when the moon rise again. If im not mistaken, bitcoin alreasy rise $2K since your post last December so if you already bought at that time, you gain profit now.
Not this year but last year was the best time or a golden time to buy more and more cryptocurrency. as far as i know about the fact that this time it's a little bit too late to buy crypto. Those people are buying it when it has reached the bottom has been getting a huge profit.
of course because last year all of the crypto experienced a drastic decline in prices so that people who buy crypto like bitcoin and altcoin in that year will definitely get a big profit this year because the market is rising and the coins are pumping up the price
