Prolly going to get downvoted, but it's not. It's 100% speculative. Look at the top 100 largest businesses you can invest in around 2011, then look at cryptocurrencies. 80% of businesses from that era are still around.... look how many cryptocurrencies that were popular that are still known (it's less than 5)

With higher risk comes higher reward, but don't let that blind you from the fact that cryptocurrencies are the riskiest investment there is.
