I know for Eth surely has future because Ethereum Enterprise Alliance...and there is quiet a bit of community around it...also its getting popular due to 2nd in market cap. But others like BAT, 1st, DNT and GNT... i have not yet seen as much momentum, my be i am just ignorant. Sure these are all great ideas, but how far are they in lauching an actual working project ? And how much likely is it to succeed...? May be as you said BAT has a proven team and has good likelihood of success. !!!
In other words how many of these will survive if there is a crypro bubble burst.. i guess...projects with sound team should survive....
