Ideally we will eventually get something like Coinbase for BTS (or Coinbase itself excepting BTS), that is, a direct fiat to BTS/BitAsset onramp that is well tested and very secure, with a lot of financial backing such that even if they get hacked they wouldnt just die and fail to repay customers.
We need a Coinbase, OKCoin, or Bitfinex type to adopt BTS. Its not as safe as holding the keys yourself, but the big players with lotso f backing are much safer than the poloniexes and bters of the world.
