So this could be the end of the bitcoin bubbles, possibly. Will a competitor come and dethrone bitcoin? Or, are we just entering a new and much smaller growth period?
This may depend on how the question of the 1 MB max blocksize limit is handled. One thing is certain without an increase in this limit,
and a hark fork is necessary for this, Bitcoin will be dethroned by a competitor. Once the limit is reached transaction fees will skyrocket as an ever growing number of transactions compete for the 1 MB space every 10 min. Fortunately Gavin Andresen understands the need for this. So do other Bitcoin developers. The real question in my mind is will they muster the necessary community consensus to make this hard fork happen?
I don't think there's any plausible scenario in which the death of Bitcoin is somehow an opportunity for some altcoin to take its place. The death of Bitcoin would be the death of cryptocurrency.
I don't agree. BTC is currently caught in the middle of two somewhat conflicting pulls: 1) a means of commerce and 2) and a deeper evolution of modern politics: that is, the changing balance of power between the individual and the state. At this point there are alts mpving full speed ahead in both these two directions, while btc seems paralyzed in the middle. In first direction, alts like Via are moving forward with sidechain possibilities and faster transactions. In the other direction, anons like Cloak and BTCD are moving rapidly towards privacy evolutions that BTC has now forsaken.
Evolution, sythesis, antithesis - this is the nature of life. BTC and crypto in general does not stand apart from this flow.
Although I agree that alt-cryptocoins can be a place for innovation, Based on the market, your conclusion about the stagnant state of BTC seems incorrect. BTC's share of the market cap continues to grow, while all of the others put together are NOT really taking any meaningful market share from BTC. This may show more of the demise of LTC rather than the demise of BTC. In conclusion, BTC seems to continue to hold its own, pretty well, and so far.
Market share will be a future result of current changes. And the departure of Peter Todd for Via signifies everything that is stagnent about BTC dev right now. Sidechains & tree chains were a no brainer innovation for BTC to knock the stuffing out of the entire alt coin market. The opportunity has hung in the air for months. Nothing happened. And now the brains are leaving to go where the action & innovation can happen. This is a red flag for any entity - creativity and energy going elsewhere because the conditions for creative growth are not there.
