Transactions

Challenges

Volatility. Security breaches. Criminal uses -Silk Road. Not widely used. Losing Your Wallet.

Undoubtedly Bitcoin has changed the way transactions occur, now even the currency is virtual. There are many challenges that still remain unanswered, since bitcoin is not regulated by any bank, so in case you lose your computer or format your hard drive then all your bitcoins just vanish. Since no bank regulation is applied on the transactions, we still need a way to make it work in such a way that there are regulated transactions and no illegal activities such as Silk Road happen again.
