I don't usually come out of my dank old cave but will for this.

There are quite a number of things that MCT has to offer I've picked what I consider to be the 3 main ones for you 

A) The ability to pair trade any listed coin with any listed coin. Meaning that currently you might have to from buying btc with your ltc/eth on coinbase transfer the btc to cryptobridge  to buy the coin you want.
On the MCT platform you're able to trade straight from any supported coin directly to any supported one you want.

B) Brand new projects can get voted in with community support. Meaning you can potentially trade coins way ahead of crappier exchanges like Cryptobridge, Graviex, Crex etc. Where lots of projects start out.
This is a huge advantage as the community are currently a fairly skeptical bunch so the chances of buying scam coins like ZOON etc gets drastically reduced.

C) There are active bounties for reporting issues with coins to the DEVs/platform so shitcoins can get delisted way faster than what is usually the case.
Being able to act faster than a general consensus confirmation of "scam" can save an exchange or escrow platform like MCT a lot of negative publicity which goes a lot further in forming general opinion than what you might expect.


I hope that gives you some idea of what you might be investing in
