Hi there,
I want to launch my own online shop which will accept bitcoin as payment but I can't decide what to sell

Please post here what would you buy for bitcoins? Watches, video games, food ?
Thanks!
The best way and easiest way is selling online game cards like steam wallets for dota2 or garena shells for league of legends because it was the main stream right now for gamers and this games are very popular.
If you want to buy anything online, then there is not a big deal in it. You can simply visit any famous online shopping store like that of amazon, eBay etc. you can even buy the things by paying with your bitcoin instead of paper money.
On the other hand, if you are planning for launching an online shop, then you have to work really hard as there are already so many shops and it is very much difficult to compete with them.
There are number of online shopping stores available. If you want to launch your own online shopping store, then this will require lot of efforts and hard work. There will be very much tough competition and the only way you can make your better name is providing quality products to your customers. In the beginning, you really need to burn your midnight oil if you want to get fruitful results.
