I just read on Btcjam blog that they are closing down: https://blog.btcjam.com/2017/05/25/btcjam-is-closing/, now I am just wondering if big players in thebitcoin industry are closing down, is there any future for bitcoin really.

I came to know about bitcoin through btcjam when i was introduced there to borrow. Eve in this forum, looks most signature campaigns might close down because of the ever rising price of bitcoin. Most of them have reduced their payout amounts for posting by more than 50%. Is this a good sign or a bad sign for the bitcoin development?
