Exactly. You can start with a $10 investment in Bitcoin; or choose another token that has promise, like perhaps Steem (the Smart Media tokens may breath new life into this).
I agree with @louisthomas that we are reaching a pivotal time and supporters will have to do more to support crypto-currencies if we want to see them succeed. I agree with what @thehutchreport says at the end of this article https://steemit.com/cryptocurrency/@thehutchreport/cryptocurrencies-the-revolution-will-not-be-televised-it-will-be-steemed
... that we may see a bit of a schizophrenic approach from governments who do not want to have their fiat currencies and banking systems overturned by cryptos, and yet they also do not want to miss out on the economic boom that the growth in cryptos may promote.
