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?
That is one site closing down, and one which was full of scams. There are many times more new sites and businesses opening up that support bitcoin than there are closing down. It is also normal for signature campaigns to reduce their payouts with rising price of bitcoin otherwise they would be flooded with requests.
