if it's for bitcoin, we all have our predictions about it. But if it's just a shitcoin that nobody gives care then it's impossible to give insights towards that coin. And this is applicable to all projects except bitcoin. I know that there must be something that OP is thinking about of what to buy and what to hold for 10 years but these people are right that there's no such platform in existence and even if there's a prediction by someone that shall happen 10 years from now, are you going to believe them?
For shitcoins, there is only one prediction for that and that is the coin will die after some years. It is not that hard to predict them but for the good coins such as bitcoin indeed that all of us has its own prediction even if it is impossible to predict accurately but close enough would be possible, I guess?
There are people that predicts bitcoin will be 300k in the next five years but for 10 years? I'd say that bitcoin will be around 500 to 600k. There are predictions for bitcoin reaching millions but I do not count them for now as that seems impossible but @OP do you wanna place a bet? Have you tried futuur? (
https://futuur.com) it is a prediction site not only for btc.
