I believe Bitcoin is slowly losing strength because at this point, it really doesn't provide anything that other crypto currencies don't provide, the only thing btc has left for it is that it was the first one and the one to go big and it was the poster boy of the crypto revolution.

Bitcoin right now is running on obsolete tech, the transaction fees are lower than what they where in December but they are relatively high compared to other cryptos(including Steem which are almost zero) and i expect BTC market dominance to hit 30% at some point in the next few months and if we have a decent alts rally, i would not be surprised if it went down to 25%.

Bitcoin has accomplished its mission but its time to pass on the mantle because the dev team doesn't seem to be up to task to make drastic changes at this point, soon a new crypto king will be crowned or maybe there won't be a new king at all but for now.... The King is dead, Long live the King!
