I really think that the creation of new E currency is a threat to bitcoin.
Like for example. Some investors may move their investments to other currency made.
If bitcoin for example has 100 investors in all, then several currency is made with the same value as bitcoin. (we say 3 currency)
then the 100 investors may move to other 3 currency to find more specific or easier way to earn money or inflate their investments.
Do you think these probability will occur?
Compared to other virtual currencies, bitcoin still dominates. I compare bitcoin with Ethereum. Bitcoin was the first digital currency, while Ethereum was born with the hope of delivering a more complete digital currency, and the Ether was just one of the smartest apps in the industry. So other currencies are not a threat to bitcoin.
