blockchain.com via Twitter: "Something "big" is coming"
Which translated into layman terms will probably come down to the following;
"We've thought of another idea to squeeze as much money as possible out of you fools still using our outdated, limited, web wallet. Stay tuned!"
Blockchain.com must cost a ton of money to be kept working, servers et al, while they don't really have any business model at all..?
It's primary function right now is to serve as a beaconing tool to show how ''shitty'' bitcoin is, by not implementing segwit, RBF. I neither would be surprised if they're trying to push BCash even harder somehow.
For those who follow BCash 'development' lately, it's clear that one of their highest priorities right now is to have ICO's and other applications be hosted and built on top of BCash. ViaBTC raised $30 million (very likely that most of these funds were coming from Bitmain, lol) with it's ICO on top of BCash, and I'm sure that that more will follow. He also said that he expects BCash to have a higher market cap than Ethereum, so we'll see where this goes.
That's a nice way to launder money. ICO-"washtrade-esque" it.
