I personally think it will still be one of the more profitable asics.
However, we'd need it to be steady and fully delivered as stated with very high uptime to make it worth it before they become worthless.
Though the S19 Pro isn't too bad either.
That is a big risk though, it would be nice if shares were available earlier, even at a higher price.
I agree, selling and buying hashing fractions can make this market more attractive.
The same also applies to the purchase and sale of the new cards to mine ethereum: activating a trading market, it could be of interest to an investor like me, 229usd for 31mh / s is 0.6usd per day, but without being able to resell your hashing l investment cannot be profitable.
The hashing fraction market makes hashnest more interesting than other cloud miners, if it no longer exists, hashnest loses interest.
