My Points:
- BTC is tracable
- BTC is having a huge txn costs
- Time taken to transfer money is more than 10 minutes
- Mining is being done with somewhat centralized servers(pools)
- Several other Alts are now at the market and they performs well in the market
- People use different currencies for different purposes
Maybe, maybe not. Or maybe no one will care in the future as long as it serves its purpose. There may be a time bitcoin will be replaced but bitcoin will never be forgotten as it was the first product of blockchain technology.
