What legitimate real world problems does Bitcoin solve? Here is what comes to mind:
- It practically eliminates transaction fees (as opposed to Credit Card, Paypal, or Bank Transfers)
- It enables international transactions within minutes, instead of days
- It enables micro transactions (due to the insignificant fees, and strong divisibility)
- It protects against unjustified freeze of funds / accounts (as opposed to with PayPal for instance)
- It mitigates currency conversion costs (when not converted to Fiat currency)
- It eliminates all middlemen between the sender and recipient (hence the reduction of cost and time)
- It prevents chargebacks for businesses (and hence the cost of goods can be lower, and less hassle for the customer to prove their identity before making a purchase for high risk goods such as gift cards)
- It is trusted more than government currency, because it is owned by the people
- It allows for easy payments (e.g. with a mobile phone and a QR code)
- You can transfer money around the clock, and even on public holidays
- It attracts new customers for businesses, customers that own and prefer to pay in Bitcoin
- At the moment, accepting Bitcoin means news coverage, and therefore free marketing for businesses
- It allows for some level of transparency because the blockchain is public, hence solving a trust problem, e.g. businesses like satoshi dice can prove that they payout what they claim to payout
- It is the most secure way to store value, if it is stored right
- It doesn't loose value do to unpredictable inflation (i.e. printing of money, quantitative easing)
- It allows for easier and more customized integration as a payment system for businesses than traditional payment systems, due to it's open source nature
Did I forget anything?
- Bitcoin is borderless: breaks down trade barriers between, for instance, the West and Africa
- You do not need a bank account to keep your savings (this helps people in undeveloped countries to build savings without access to banks)
- Pledged payments: if for example 100 BTC is pledged by a group of users, then the transaction is broadcast (nice feature for Kickstarter, Indiegogo, FundedByMe.com etc.)
- 2-out-of-3 escrow payments without human involvement
- You can backup your savings! Bitcoins don't get lost in a fire. If your house burns down then your paper $$ stash is gone, but your Bitcoins are "safe" in Google Drive and Dropbox
- Pay a "Domino's Pizza Drone' with Bitcoins and it'll fly your pizza to your 5th floor appartment window - no handling credit cards, no cash, just perfect
