You have a point, but I think you're overlooking that growth is not only determined by how much money you can throw at it. LC has way more money than they need right now, they have said so multiple times. The chips currently on its way were already payed before all of us even knew LC existed, and the IPO money goes to development of the next generation (65nm) ASIC.
For right now they have plenty of money which means they can sell their chips for cheaper if necessary and that is all good. It also means they can produce more chips if difficulty goes up and that is also good. Right now they are on target and there are no complaints about that right now but 2014 is a new year with new competition and much higher difficulty.
When they use 30% of their mining income to fund further growth, I believe it will be enough by far.
For a couple years maybe. It wont be enough for as long as people think. They wont be able to make more efficient chips after physical limits are reached and nothing stops a big player from deciding a few years from now to get in on ASICs. If that happens everything can change overnight. What if a video game company like Nintendo decided to release a successor to the Wii which mines Bitcoins and lets the user download free games? What if Sony gets in on it? There are a lot of chip companies with a lot of money who could decide to mine Bitcoins.
If we pool our resources together to give them, say, another million dollars, that won't necessarily speed up anything. These things not only take money, they take time and skill.
I'm not talking about speeding anything up. I'm talking about security in knowing that Labcoin will survive the next 5-6 years. Right now I can only see it maintaining its position for 2-3 years and that is if everything this year goes how they plan.
The speed can be increased by increasing infrasctructure, hiring more personel etc., but still only at a limited rate.
I was not talking about that. I'm talking about cheaper chips, not just smaller.
If they calculate that the income from 30% of the mining&hardware sales is enough to sustain their growth, then that's fine. And I see no reason why it shouldn't be.
Speculating that Intel and AMD might jump into this and kill all the current ASIC companies in bitcoin is really a bit far-fetched IMHO.
It's far fetched in 2013, it's not far fetched in 2016. ASICs were far fetched in 2012 back when everyone was GPU mining. Intel, AMD or anyone could flood the market with chips and hashrate. Any chip company can make an ASIC and lower the price down to a level so everyone has to buy theirs. I don't think that will happen for the next 3 years but after that it's anyones guess.
