This was a brilliant move and you will be paid very well in the end. 

Most MSC on the sell side are from 'day traders' and JR and programmers.  Almost nobody has coins for sale as a result in loss of faith in the project.  Mastercoin has money in the bank, a very sexy new DEx coming soon, better than expected wallets, and lots of momentum.  The price has been seriously pushed down because JR needed money and a few programmers are taking salary from the market.  I am pretty sure MSC is going to be crazy by summer.  If significant use adoption occurs in the fall, your 100MSC will be enough to retire on in most countries.
