I suppose it depends where you draw the line between trading and investing, but technically, any one who buys or sells a cryptocurrency is trading.
SBD is essentially pegged to the US Dollar which makes it a very attractive hedge. It's also a hedge that doesn't require you to trust the issuer, as it's not backed by $1 USD, it's backed by $1 worth of STEEM.
If you wanted to sell your crypto investments temporarily, without having the hassle of going back into Crypto from fiat down the track, SBD would make a lot of sense.
Hmm yeah, that makes a lot of sense! There isn't any other cryptocurrency that is pegged to the dollar, is there? Thanks for explaining it :-)
