I think it's not free or it's a free for use? I am not trader but I am interested to know about.
It is free for the first month. After the first month, for full features you have to subscribe. If not, you can continue using it for free, but with certain restrictions.
Subscription pricing is here:

Since crypto currency support is new to us, we have not decided yet what restrictions will be modified for the free version of MT for crypto sites. But, as you can see, the subscriptions are inexpensive enough that for traders they should be an insignificant expense.
Oh - and crypto support is not in production yet, so download/install the beta. Production is coming shortly.
We're working on trading integration (so you will be able to trade through those exchanges from within the program, either the regular way - through trading tickets - or visually on charts or on DOM). There are enough little features that are specific to cryptocurrencies (such as tiny traded quantities etc) that we have to modify quite a few features in our code to accommodate them.
