That's not a bad idea, but I would caution putting all of your investments into two sectors - one of them being cryptos.
However, I do believe that having a pegged instrument like SBDs makes it much easier and relatively "safer" (I use that term loosely) to hold cryptocurrencies. Not needing to cash out holdings in order to avoid or mitigate volatility is a huge plus and gives STEEM/SBD an advantage over pretty much all other cryptos.
Even if the social media aspect of this doesn't turn out well, I think the blockchain and SBDs offer a huge amount of potential and potential value.
