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?
The probability is 0 because new coins that are made are not well established and it will took many years before or could manage to get with the same price with bitcoin.
Investors of bitcoin doesnt necessarily move 100% all their money to new coins because the probability of the coin will fall down has a huge percentage.
Investors think about how to make more money if they have doubt on the coins they will not invest on it.
