If someone had told you during 2015 that Bitcoin will exceed over $100k one day and you should invest in it as at then. Would you have believed?
It depend how the someone take present the explanation that will make me to believe that BTC price will reach $100k in 2025, and it will make me to prepare in that 2015 and 2016 to invest to invest in BTC to be among the Bitcoiners that hodl from 2016 to 2025 to witnessthe $100k. This is decentralized asset you are talking about op, which is not control by the government or financial institution, because it will be hard for someone to convince you to invest in BTC in 2015 without you ignore the person or call the person scammer because you don't know how it will to cause user profits.
Now that I have idea on BTC investment, I will not wait for people to tell me to invest in BTC before I will invest, because I no the price will hit above $200k or $1m in the future to make some people to regret for not invest in BTC at this current price.
