The price on Mineority is $5750. I think that in the current market, Crypto transactions do not make sense. Credit Card or PayPal may interest more people. Almost 1 BTC per FPGA!

They do make LOTS of sense for the sellers, because they think crypto will recover, at least partly.

So you pay 20ETH for an FPGA, one year later ETH has doubled (meaning right now going to 600$), then they exchange crypto for FIAT and get 12000$. Clever move.

if that's true, than they shouldn't sell fpga, just buy eth and wait for it to rise.

It's the logic that doesn't work.
"better being paid in crypto because it will rise" doesn't make sense.
because if you get fiat instead, just buy crypto ;-)

You don't sell, you don't get margin and benefits.

The CVP-13 is about 50% faster than a BCU1525 on the algorithms that fit in both BCU1525 and CVP-13, meaning that the ROI on both boards is very similar.

The improved ROI comes from algorithms that only fit in the CVP-13, or that only fit in daisy-chained CVP-13's.

If you look at X17 for example that only fits in the CVP-13 (approx 710MH/s), the ROI is about twice as good as the BCU1525.  However there aren't that many algorithms that fit in the CVP-13 that don't fit in the BCU1525.  The equihash variants can be done (fast) with daisy chained CVP-13's.

Plus, if you immersion cool your BCU1525, you can make up some of the performance gap.

Multi-card bitstreams are difficult to develop, and to be honest I'm not even sure they are scaleable to large farms.  You need to load a different bitstream into each card, then create a config file on the PC which tells the PC which cards are connected together, and obviously if one card goes down or fails, both cards are down because they cannot calculate a hash result on their own.  It does have potential for really high profits for the small-scale miner, but I doubt a 200 FPGA farm would bother with multi-card bitstreams, especially if you need 4 or 8 cards daisy chained together.  Again, with 8 cards daisy chained, if something goes wrong with 1 card, then the whole rig is down.

A customer looking for a turnkey FPGA solution can buy 5 BCUs from Mineority (https://store.mineority.io/sqrl/bcu1525/), with 3-years hosting, 3-years warranty, efuse set for encrypted bitstreams and free QSFP28 cables (if they run multi-card algos).... for less than the price of a NR104 with 4 cards, 1-year warranty, 1-year hosting, no efuse, no cables.

Or are 4 NR1525M's going to out-hash 5 BCU1525's? (and by such a large amount, that it's worth paying thousands more?)

The Mineority+BCU combo beats hands down the NocRoom NR104 offering.

Over-priced, with outlandish claims of value and ROI to boot. Try to answer the real questions in your thread rather than deleting them. Until then, scam alert.

...and video of a box running fans is joke right?

If you have bitstreams that come with this, please share the hashrate to the community.
