If the product isn't standing on it's own feet at that point, why would they need to?
You probably can count that as a failed product if it still needs another funding round.
The point is that I have doubts that premined coins - some few exceptions like ETH and XRP aside - will be able to really stand on their own feet, due to the pychological problem I pointed out above - that the community members will never be incentived enough to really "take over" the coin and its development because they know that most benefit went to a single team.
Most cryptocurrencies should also not really be viewed as a "product" - the only ones that should, are utility and security tokens, and these are some of the few use cases I consider premines legit.
General purpose cryptos should have the character of a "community" without any entity with more rights than the others.
But sponsors like Blockstream doesn't just arrive out of nowhere. Bitcoin was running several years before that was even founded. These days if you want to launch another pow coin without guaranteed incentives to devs, i doubt that many would risk many years of their lives for a project battling with thousands of projects, without any certainty if you ever get paid for it.
You're correct in that it is much
easier to launch a cryptocurrency with premine, as you don't have to do fundraising with other methods, or pay for mining equipment in the case of PoW coins.
But in this case I consider the easy way to not be the best.
There are methods which can help to fund a cryptocurrency without premining it. I plan to write an article about them. The most well known is of course to mine at the start when the coin is not well known. As you'll probably expect I also disapprove blatant instamining - mining before any announcement/code publishing - but I consider it legit to launch an unambitious ANN, or even an ANN in a language not English to build up a regional community first while benefitting from that not the whole world will try to mine your coin (I'm not a friend of Anglocentrism).
And I know some small cryptos without premine which are still able to pay developers simply through donations, and for several years (an example is PPC). There is also a much higher incentive to improve the coin for free if if isn't premined.
Ok, good point. But i still see many advantages for premine. For example, if i wanted to form a team for a cutting edge new tech from scratch, that's formed from from talented developers, cryptographers, senior researchers, cryptography researchers, marketers, and later legal advisors, HR and god knows what. Then i am not going to get them working full day for me for fun of being a part of something new. Bitcoin had an advance of being the first and attracting right people. Pulling that off now would be a miracle.
Well there were some examples for cryptos with "cutting edge new tech" launched without premine, for example Grin, which is one of the most advanced cryptos I know (no, I'm not talking about the PBFT derivatives which use
tech from 1999, like ETH, Avalanche, Cardano, Tron etc.). Grin had the bad luck that it was 51% attacked, but is slowly recovering.
And the things I marked in bold are not necessary for decentralized cryptocurrencies. And if a crypto isn't decentralized, why are you needing a cryptocurrency? You could also use a client-server structure like PayPal ...
