Whitepaper to product: how long does the average crypto take to the real world?

Hi. I have an interest in computer science. This naturally brings me here because there is so much interesting work going on.
Where would be the best place to find the following information :
* when was a crypto created.

• when was its whitepaper released.

• do they have a product that is being used?

I have a total of $50 invested in Crypto (mostly for test purposes), but I think there is a problem in the space.

People here may consider themselves "in at the start", but bitcoin is over a decade old.

Its past time that investment in the space was better routed.

• projects being used today should have a higher investment percentage. This includes bitcoin (sorry nano friends) because bitcoin is used even if not for its intended purpose.

• projects in the process of being adopted should be next priority: think bat, VET. These projects are already being used, just not at 100%.

• the smallest percentage should be attributed to projects that do not have a working product, or are no where near finishing.

We need to stop treating this space like a giant casino. Ironically investment in the correct ratio gives the best chance for yield in the event of an expanding market. When new money finally enters this space its probably not going to be to the most shilled coin.

I intend to create a ranked resource that shows where projects are in reality, so any info about my bullet pointed questions would be helpful.

Thanks.
