Hold on, hold on... If the price does spike early due to limited supply, that's what will trigger people who already generate solar to start submitting their claims in earnest which will start adding to the supply (coins in circulation). That will keep the price in check from going too high in the short term because many of those claimants will be more inclined to sell or be inclined to accept SLR as payment and get transactions under way.
I agree. I think this is one of the excellent features of §SLR from an economic perspective, that the price will tend to be self-regulating after it reaches a certain level that's high enough to create lots of interest among generators. This will help it to be more useful and stable as a currency, rather than only as an investment.
I expect we'll see 5 or 10 cents per §SLR by the end of this year, and at least $1 by the end of next year. The growth curve could be very steep for the next couple of years, because of (1) limited supply (declining mining rewards, not much generator granting yet); (2) the crypto community eventually rediscovering this coin; (3) big investors outside the crypto community getting in when volume increases and it will become possible to take large positions efficiently.
Beyond the $1 level, I'm not going to make any predictions, but the target $20-30 level could potentially be reached after a few more years. To do so, §SLR would have to surpass Bitcoin's market cap, but I think that's possible in the long term, after major players in the solar energy industry start backing this coin and integrating it with metering systems, etc.
