- Very high shipping costs
- Very long delivery time.
I think if this can not be overcome, it will be difficult to make bitcoin as the world currency.
Both of these issues remain my mind whether anyone can cope or never will
Disadvantages of bitcoin is a lack of securities to all account and wallet in your hardware, if we do some investment and trading here we need always be use 2 options, it needs to make the way of saving in Bank Deposit and at the same time earning a lot of income because of Virtual currency of Bitcoin in every seconds, it is possible all our effort is being nothing if we did not be careful about this... my advice here is don't trust the anonymous person with suddenly pop up of your device, make some investigate first before you do it... thanks
