We all know that there is a hard limit to the number of bitcoins that could ever be minted. That limit is almost 21 million BTC (minus a few Satoshis). Long term holders hope that this limit will cause the values of their coins to go up considerably due to increasing demand.
However, there is no limit to the number of shit coins that can be invented. In fact the ETH shit coin now has a market cap that is of the same order of magnitude as BTC. Furthermore it is an inflationary coin.
If many people move their capital to these alts won't this negate the benefits of the 21 million BTC limit for Bitcoin holders?
Scarcity value is the economic factor that increases an item's relative price based more upon its relatively low supply.
Bitcoins are divisible so fixed supply or a huge increase is not going to be a big issue.
Right now bitcoin is a speculative asset. A few economists have predicted that bitcoin price would reach up to $100,000 in the next 10 years, now this is backed just by speculation.
Cornering the marketIn finance, to corner the market is to get sufficient control of a particular stock, commodity, or other asset to allow the price to be manipulated. Another definition: "To have the greatest market share in a particular industry without having a monopoly".
Speculative attackA speculative attack has much in common with cornering the market, as it involves building up a large directional position in the hope of exiting at a better price. As such, it runs the same risk: a speculative attack relies entirely on the market reacting to the attack by continuing the move that has been engineered for profits to be made by the attackers. In a market that is not susceptible, the reaction of the market may instead be to take advantage of the price change, by taking opposing positions and reversing the engineered move.
Now a currency or asset backed only by speculation is prone to cornering the market and speculative attacks, pumps and dumps and in the long-term events like these has the possibility to negatively impact bitcoins market.
Like I said, fixed supply would never be a hindrance to bitcoins growth, but driven only by speculation will be, technical and price stability is a necessity if bitcoin needs to stay on top.
