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
If we make an analogy to compare digital assets,it is more accurate to say that bitcoin is like gold and altcoins are like platinum or silver. They are at thr back of bitcoins. But bitcoins and altcoins are both valuable for different reasons as digital assets.
And for me Bitcoin will remain and none of the altcoins could replaced bitcoin. Because bitcoin is always be the original digital asset. It solved the problem of trust-less scarcity on the internet. It is also a survivor. Bitcoin survived from 9 years of constant attack,bad press,attempted government regulation,an onslaught of altcoins and tons of ICO tokens. Despite all of this bitcoin continues to grow and remains the purest,strogest,most decentralized,most valuable,most leaderless version of cryptocurrency. Bitcoin is always the best digital asset and no altcoins can replaced.
