Ya, the less long you hold it for, the less likely it is to go kaput on you. But I'm saying a year as in that might be when it seems like the crypto market has bottomed and you'd want to buy back in.

I can hold Tether for a few weeks and feel pretty comfortable, but also the crypto market won't have dipped as much in that period.

Ya, I'd like to hold SBD, but indeed, it doesn't seem guaranteed to hold its peg.

Tether works so well because it's literally just Bitfinex people promising that they have a dollar to backup every Tether that they create, as far as I know. That's why it holds at a dollar. But the risk is you're trusting them, that they really have all these dollars and won't run off with it.
