After long search and confusion a friend @Mehulbanterfam@bbs  enlightened  me and i finally find out why when i withdraw from BBS to wombat e receive very little money.

Recently i withdraw some money from BBS, i had 220$ in BBS token and when i withdraw to Wombat you cant see at first how much you received until you convert BBS token to EOS.

When i converted from BBS token to EOS from 220$ i received only around 160$ (don't know exact value) and i was confused why so much fee, at first though that it was fee from BBS but i was wrong. 

You can see here in Defibox the value of BBS token is not real value it's $0.0234 

You can see here in BBS the token has real value $0.0306 

So for example in BBS if you have 5000 BBS token the value is 5000 * 0.0306 = $153

Same amount in Defibox you will not get $153 but 117     like this 5000 * 0.0234 = 117

So i know that it was not like this before, because when i swaped before on Defibox i got fair BBS token value, now we have to pay 30% for system fee and almost 30% on Defibox and in my opinion it's a lot.

For example if you earn $300 on BBS in best case with deduction you will have $120 in your pocket.

I hope that Defibox price raises or BBS token gets listed in some better exchange because Defibox hurts us a lot.

I think that this is the problem, please tell me somebody that i am wrong and there is solution
