Are there any good websites or platforms predicting where crypto will be in value 10 yrs from now?
Hope you realize that in the free market, no one can predict the price of cryptocurrencies with so big advance. Cryptocurrency price predictions can be based on technical analysis or entirely free speculation. There are influencers (most often on YouTube) who claim to be experts. Never follow their suggestions, as they are 99% of the time a scam.
So the answer to your question is no, there is no such platform or website.
