The promotion through Television might create a negative impact on the growth of bitcoin. It's good to promote once we have made perfect solution to handle large volume of transactions without getting stuck to the network. The reason is that when promoting is done, surely we can expect a big number of users into the network which might cause a downfall because of transaction delay and minor issues associated with it.
I understand that you want to promote only finished product, but Bitcoin will never be perfect or finished. It's constantly being developed.
We won't have Bitcoin commercials airing on TV but if we had. How exactly it would create negative impact?
Bitcoin commercials would be created exactly to bring more users to BTC.
If anything, I see it that way, more BTC users will induce higher motivation to upgrade network, not the other way around.
