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?
That is not true, it is not a threat. First of, there are a lot of e-currencies already before bitcoins were created. The truth is, bitcoins are the threat to e-currencies. As bitcoins offer much more than what conventional e-currencies offer. Then there is the fact that e-currencies are 100% centralized as compared to bitcoins which are decentralized. In e-currencies, the company can just suddenly say "your funds are forfeited". This can be seen with paypal actually.
