I must say that these are quite huge milestones, but they are achievable. In as much as I would love to pinpoint a particular coin as the one with the highest chance of reaching the milestone stated, I would love to point fee things out.
BTC at a $100,000 price value is feasible but wouldn't come easily. Ethereum $10,000 will happen if the ethereum 2.0 is fully functional by the third quarter of the year. Solana can easily hit $500 considering the projects being built on it.
As for Shiba Inu, I don't see it reaching that Mark due to lack of use cases. A 50% rise will trigger a massive sell-off that will crumble the price.

In the end, I will go for Ripple at $2. The very feasible lawsuit victory will make this possible.
