Lisk, because I think the familiarity of javascript will make it much easier for developers to work on the platform and create dapps, then will other similar crypto offerings. Whether or not that is true we will see. There are likely more inherent security issues due to it being built with javascript too so that may hold its value back. Nevertheless, I actually like the slow and steady development that has been taking place in that project and I foresee large long-term growth.

And of course I hold a bit of STEEM as well ( I see similar huge long term value here, and by long term I mean on the scale of years ), and BTC.
