I can't seem to find development bounties in bounty threads.
Does anyone know of where I can find good development bounties?
Or is the whole of crypto not actually building products

you can find that ins some trusted bounties i.e cartesi and it has already created a good product and you can also try to use the product too. You can also try to take a look at arcs chain too and the latest project who have already developed product like oikos should be considered as a good project too
