Believing is putting faith in something or someone. Yes I do believe in bitcoin. Although it cannot be seen physically I can use it for earning something and gaining money to get some of my needs.
for me im also believe in bitcoin because i saw bitcoin price is yearly increased.. and i think it will increase more in the future ..
and bitcoin is very popular and they use bitcoin also as payment from other site.. so that bitcoin will be great in the future..
I think you've got the concept pretty well down pat.
As it stands, Bitcoin is poised to become an increasingly more popular currency, and a lot of companies are still taking note of it and looking to expand into it. JP Morgan has the discounts for gold purchases in Bitcoin, other companies are opening their wallets for Bitcoin, among others.
In my opinion, Bitcoin is something that seems like it will perform into the future.
