BTWTY, is an index fund with a very successful lifespan. Did you read up on it? ARISTO is a coin connected with the operators of BitShares and will be around for a long time. Both are only available on the bitshares platform. BTWTY is proving to be a very successful token. ARISTO is a novelty which shows promise. Promise which is connected with the success of the BitShares platform.
I also made nearly 50% on ARISTO last week and a good chunk on BTWTY. ;)
Looks like the owner of ARISTO is selling off half the supply. Good call. lol
