We are seeing again a dip and chances are that majority of alt coins will take a dip along with BTC. Its good to see whats safe price to buy BOOM and keep it in your portfolio.
DYOR if you really wanna do this. My analysis is based only on recent price variation of BOOM.
And now the average Altcoin has started to increase again in a few percent where it happens simultaneously with the increase in BTC as well, but whether the next decline will also occur again in the market later, I also don't know, because many predictions are now wrong from what what some people say.
There are alt coins like Eth, LTC etc that are directly linked with BTC price volatility. When BTC goes up they also go up and down accordingly. But if see sleeping coins like BOOM, they have there spike once in a while during BTC bull run. Its wise to keep them in your list and more wisely buy them at right price.
