I think the most straightforward solution would be to simply leave your current holdings alone. Let them sit. But stop buying them. Let them ride.

However, for future fiat investment, go 100% all Steem.

That way, you can have your cake and eat it too.

Or if you exchange some BTC for Steem right now, then consider that a hole in the BTC bucket that needs to be filled. Make a plan to replace the BTC over time.

I went through a similar struggle not that long ago. I didn't want to sell off my BTC, EOS, ETH, or whatever...but I just wasn't excited about them like I was for Steem. They didn't have the same utility value or emotional spark that Steem gave me. So I stopped actively buying them. If I buy crypto, it's Steem.

As we get closer to Ethereum switching to Proof of Stake, I'm sure I'll be tempted to buy a bit more ETH. But for now, I'm pretty satisfied with my decision.

Ultimately, if I'm honest with myself, the decision is probably based less on sound investment strategy and more on whether I get to PLAY with my crypto. I want to have fun with it. I want to ride it like a new bike. Steem satisfies the kid in me. I get to DO stuff with it. I get to actively contribute to the success of the blockchain. Maybe not in a BIG way...but that's okay. Chances are, it will be significantly more influence than I'll ever get with Bitcoin.

You probably shouldn't turn your portfolio upside-down. But you definitely shouldn't shrug off your desire to get serious about an investment that could support your values and life goals. Most investments are strictly for financial gain. That makes sense. But it's always good to have at least one investment that's about more. Where it's about something you believe in and you're willing to fight for.

At that point, it becomes less about economic models and more about whether you're ready to turn a social experiment into a serious passion project.
