What's preventing Bitcoins from being accepted as mainstream payment forms? I'm working on a new blockchain and would like to learn what drawbacks of Bitcoin urgently need to be improved Wink
Although Bitcoin is new advance thing but it has some disadvantage for which it is ban in many country. First of all it is not widely accepted. Due to this you can't access it anywhere. You can only use it in selected place only. And for its access Internet and electricity must needed. Another disadvantage of Bitcoin is its volatile nature, due to this many people looses hope upon it 
. Due to its digital nature all the bitcoin related information store in a hard drive. If hardware crash or virus corrupt those data then their is no way to get it back. And it has no physical evidence too. Another thing is bitcoin is still too complicated to understand.
