I have this information since spring this year, don't ask me for proof as I won't give any.
You don't need to be psychic to realise that Bitcoin may not be the dominant crypto in the distant future.
As for no more bubbles... she is wrong I am afraid.

Why it wouldn't be the dominant crypto in the distant future, tho?
What is Bitcoin doing wrong that another coin would do better?
Thats what should be asking, not some psychic stuff.
It has nothing to do with being better. The Crypto community can't even reach consensus on what units to use for smaller amounts of Bitcoin, no sign of bits or millibits or whatever gaining any transaction in the industry. In what situation do you see coinbase, circle, bitpay, bitstamp etc all replacing Bitcoin with an altcoin, how would they all reach consensus on one of the 100s out there. How long would it take? what percentage of Bitcoins market cap would this other coin have to have for this to even be considered, I reckon it would have to have exceeded it.
If that's your fear, just hodl Bitcoin. If any other coin gets to 1/4 market cap of Bitcoin move 1/4 of your Bitcoin worth into it and you'll have as much of that as you did of Bitcoin. Something like this would take months if not years to happen, you'll have plenty of time to switch and it's a stupid reason not to hodl Bitcoin now.
