While Bitcoin there are a few scaling options, it appears that a number of Bitcoin investors have been switching to Altcoins, and may not switch back to Bitcoins any time soon .
What will happen if investors continuously switch to altcoins? Will bitcoin crash ?
Now is really hard moment for bitcoin because of high fees, I really think continue or not using of bitcoin because for small transactions it's terrible. Investing in bitcoin mining is great idea and still bitcoin exchange or some btc idea is still good. For example if someone will offer reduced transaction fee, it will attract many customer. Bitcoin gained huge trust and is more known than any altcoin. Still don't think people will choose any altcoin over bitcoin because for example ethereum's hard fork was reason of losing many people, they didn't like that. Also imagine zcash, what was it's first price and what's now, so huge fall in days? It's not fair and that's why bitcoin is still popular, trust is main factor.
If discussing the current high fee conditions, altcoin has a good chance, I exchange bitcoin to dogecoin and send it to another wallet with no problem and with a small fee. I think it's time for altcoin to play more actively until the bitcoin condition improves as before.
