Nano takes like 4 seconds to confirm and has zero fees for transfer. It's really a no-brainer, but unfortunately this Bitgrail thing is going to muddy the waters for a long time.
BTC survived Mt. Gox and Bitfinex, NEM survived Coincheck, and fiat currencies survived many a bank robbery. Investor perception is low because the theft hurt early adopters, but I think that the technology will shine through sooner rather than later.
