Ummmm.... NO.
The way exchanges get rich currently is that they sell / trade cryptos in excess of what they really have. We are about to see a lot of exchanges suddenly explode. Suddenly have a "theft" just like Mt.Gox. And those who do not have their cryptos in their own wallet will find they have nothing.
However, i have a brilliant sollution for you.
An exchange called BitShares.
bitshares.org
They are actually what Blocktrades trades through.
An exchange that has multiple currencies. (including STEEM and SBD)
A cryptocurrency that is used to swap between other cryptos and is a good store itself.
Its only problem is not many traders. So, come, join us.
Blocktrades was discussed in the post. It is an OTC exchange. An OTC exchange will never be able to compete with the volume of a centralized exchange. Unfortunately it will never be large enough to make any difference.
Blocktrades is not BitShares. So, i do not know what you are referring to.
