The amount of altcoin is now much, they can compete to occupy the market share of BTC, but to make the price of BTC is reduced is not possible, altcoin prices are still dependent on BTC prices, Crypto market is always dominated by BTC .
I think the problem is is popular in the digital world, but still many people don't know what is , in this situation if we started to teach any other altcoin to people they will not listen. People want only profitable things. How the users increase in the same way, the coin also grows. The best example is . In future may be any other coin can beat but now it is not possible.
I don't see any altcoins standing a chance against Bitcoin to be the top leader of the crypto-currency market, Bitcoin values are constantly rising every few months and this meant most of the traders are putting their attention on Bitcoin, even the new comers who just get into crypto-currency are asking questions mostly related to Bitcoin.
