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?
Bitcoin and other crypto currencies are different in many ways. Bitcoin is the first, original and have the highest price of them all. There are many coins now in the market but none has overrun the bitcoin. Investors will still stuck to Bitcoin because it has proven already in the market.
