Spending bitcoins is very easy for me because i exactly know what i want to do with them i want to go on a world tour and i have that advice also from someone who is on this forum someone ever posted what if you could go on a world tout and i knew i wanted that.
Its hard to spend bitcoin, because you cant find a site or place where it is being accepted. But if you have the Bitcoin debit card that is being issued out by companies like Xapo, Coinbase, Bitpay and the rest of them (which functions as banks for Bitcoin) then every impossible things becomes possible. I have been able to do a lot of things with Xapo debit card, the only problem is the fees.
I can use it on Playstore and iTunes, I can also use it in online stores where credit cards/debit card are required. But spending it wont make the lots of people adopt it, Bitcoin will grow whenever it meant to grow, you cant do anything about that one.
Today, spending your Bitcoin without exchange to FIAT is really hard, but if Bitcoin can becomes famous, the Bitcoin community will grow more and more retailer will also accept Bitcoin to earn more it. In future, my imagination can become the truth if the devs of Bitcoin all want to help this cryptocurrency become the strongest cryptocurrency without old system as now.
