Not to be a downer but isn't this recycler just the Dev doing the busy work for others? If someone wanted to own MAST and they held other coins, then they can simply sell them and buy MAST and most probably get a better exchange rate and not have to worry about a 3rd party holding their money. Not sure what the value add is other than you hope since its supposed to be easy maybe people will use it because they are too lazy and won't buy MAST on the exchange but they might use the recycler (guy who sells your coins for you)

IMO this is a cute idea but needs an anonimizer built on top of it for it to have any real value other than a new take on a multipool that pays out in MAST. Kinda neat, but not much more.
P.S. you also have to get people to want to convert to MAST in the first place and that comes with adding features like privacy, ease of use, and merchant point of sale integration, sms sending of MAST.....stuff like that. Add something like this into the recycler and you are good to go. Atleast for v1 anonimity.
