300k bytecoins are going for about 15 or 16 Satoshis each which would be 0.045-0.048BTC. Are you also offering the doge as collateral?
If he is not offering the DOGE as well, then his Collateral is still not enough.
Imho this Loan Request become more and more "difficult" and more complicated, without any major issue.
Just Op, don't understand some things around here and he don't want to listen.
With this behavior, i don't see this Request ending in a positive manner.
Good luck though...
He indeed is not listening, because he is only semiliterate and probably has other cognitive deficiencies as well. And this already isn't going well, with the good ship mexxer-2 having negged him and OP not having gotten any bites. The neg is fully deserved, too. This gentleman didn't read the rules of the clubhouse, which are affixed in large print to the front door.
