I think looking at the crypto markets in general, there's a birds-eye view of how Bitcoin and other cryptocurrencies are performing. Considering the last weeks bump in price and the price jump since 2-3 days ago, we're noticing a trend that looks to be bringing in the "Bull run" causing altcoins to rise by a large percentage, where as Bitcoin is still slowly making it way out of the Bear markets. The surprising factor here isn't about the previous weeks rise, but is as to even with a large trading volume we're noticing a small percentage increase in Bitcoin's price as compared to the altcoins. This isn't necessarily a worrying factor as it's just start of Q2 of 2018. We should mostly be seeing a back to back weekly increase in the price of Bitcoin over the next couple of months.
