A very interesting post. Although I suppose the single most important thing is just to do your research before investing. Hurrying to make any single investment will probably mean that you just end up investing in what ever other people are investing in. And in my opinion those aren't good investments. Altough in the cryptocurrency world everything seems to go up currently.
I also agree that starting with a small amount will be good. Unless you're a seasoned investor, in which case you can probably figure out how to invest in cryptocurrencies as well. There are things you can analyze and by doing so figure out what are good investments.
