do you agree that the growing number of altcoins will eventually make bitcoin price go down since even small amounts of users money go to them?
No. I think the opposite (bitcoin price go up) will more likely to happenwhy? because most altcoins markets are based on BTC, or ETH, LTC and other prominent coins
even if new coins accepting fiat money on ICO stage, they will open trade market for BTC
BTC in crypto world is like US$ in real world. Most (if not all) countries accept US$ in their local currency exchange
The same for BTC in crypto world, no altcoins will refuse exchange to BTC
