Centralized exchanges are dangerous, localbitcoins is the way forward. In certain countries, you can even use 3rd party mobile payment to trade with private people on localbitcoins and have instant delivery, much faster than an exchange which takes days to deposit. And once you know how to use localbitcoins, you can use it in any country. However, they should change to multisig to increase their security, they have also been hacked before
The interesting thing is there are now alternatives of LocalBitcoins as well. These are
www.BitQuick.co &
www.100bit.co.in. Though it seems BitQuick.co is US only and have a few division elsewhere, 100bit.co.in is a truly global platform for direct traders.
Interesting, although I would guess that they all suffer the same problem that eBay clones have vs. eBay. LocalBitcoins has the most buyers and sellers so people will naturally gravitate towards it over its rivals. This in turn makes LocalBitcoins even more attractive for buyers and sellers and thus even more popular and so more people will use it in a kind of positive feedback loop.
