Is there any other transferable coin that will be used for digital and everyday use? How to make crypto more accessible for p2p and exchanges?

I'm new to crypto and don't know much at all, however you please weigh in on my plebeian analysis.

So we all know bitcoin is likely here to stay as it's now infused as a major financial asset and will rise in the community 5 years to new heights. However there are very few actually making long-term analysis, It's all get rich investment hype or scams ect. With the rise of ai quantum computers and more the security and use of cryptocurrency is becoming apparent. Bitcoin will hit 1mil within 20 years.

However bitcoins system cannot handle the amount of transactions in a society for everyday use only large amounts on big purchase . .

That's why there must be a integrated 2d level. One that has a faster but More secure transfer and even storage as visa as a decentralised. Asset. Having 2 separate accounts. And not only that, but development of real assets like crypto replacing the concept of vbucks ect gaming ect. And more.

However

Volatility of the market will remain until a set path to the future remains unclear on individual assets. One will not utilise a unstable asset. One reason butcoin is bit and being used now is its future looks bright.

So. Is there a better coin like etherium or bitcoincash to invest in early that's likely to take off as a second to bitcoin? As use will drive up prices from current lvl.
