Am I getting this wrong?
Well, from what I understood, OP wanted the projects merge, not the buyers.
For all the buyers buy only Bitcoin you basically need to either convince everybody only buy bitcoin (not possible) or somehow disallow/deny existence to all the other crypto projects (also not possible).
And making "what if" calculations for things that will not happen are, sorry, pointless...
when each cake has its own recipe and method of making it we cannot make it with one concept because it will taste different even though we can sell it for one price and one currency and sometimes this difference is what makes it valuable in today's systems crypto and blockchain.
And together time bitcoin will pass $100,000, will we get it...
