Yes, I think that now is the time to buy, now the price fluctuates and is not the highest, if you want to keep and sell after a long time, now is the chance.
as we can see im the price list of all coins. the price of alternative coins really low. and the ethereum has in the situation that it only range the price at 230$ . but i am sire for other it os good to biy and others not good because they hold for a long term and the result is the price is not good. but many changes has coming i am sure
