Of course. Now is the best time to buy altcoins. The price of bitcoin in the flat, 53% bitcoin domination, I think that the pamp will soon be waiting for us. Of course, nothing can be said for sure, but I'm now buying altcoins, so that then I would not regret, when their price starts to grow rapidly.
Not now is the best time, that 53% bitcoin dominance is keep on increasing that makes the altcoins more struggling in price massice dumping. I will not be confident to buy any altcoin at this moment right now because it might be stumbled for a lower price level.
Of course you are right. Prices may fall even lower, and may not fall. Let's objectively assess the current situation. Many factors now show that the price of bitcoin should go up. But no one knows exactly whether it will go up or not. We just build our assumptions.
On the other hand, prices for altcoins are now very low, so buying now promising coins will definitely be profitable. In any case, relying on all sorts of assumptions, it is more reasonable to begin buying right now, according to the following scheme: for example, 40% to buy now, 30% to buy in a few days, when the price decreases and 30% to buy after some time, when the price will decrease again. Of course, this option requires a lot of time for its implementation, but it's better than just waiting for the price to become lower (because it may not be lower) or buy it right now at the prices that are available.
This option also doesn't guarantee that you will buy a coin at the best price, but if you don't buy it now or in the near future, soon such a possibility may not be available.
