btc-alpha is not the main exchange I use, but it has relatively good features. The demo trading section, which is easily accessible from the site menu, can be a higher education system for those who want to learn to trade on a trial basis.
Of course, if the facilities of this exchange were more, it would offer more different types of trades, it could be one of the best. The security of this exchange is really good and by entering in two stages, you can safely keep your assets in it.
