Brilliant post and a great story about your journey into the crypto world. I came much later than you, buying my first BTC (A physical Casascius coin) when it was over $2000.
I have written alot about BTC and very recently about steem.
It's a good idea to hold several alt coins. If you are doing it seriously you should read each white paper and write down why you think the alt-coin will rise in price. Here is an example:
"I think bitcoin will rise because it is the king-daddy of crypto and has the brand name. More people are going to want it in the future."
Here's another example
"I think the price of steem will rise as many more people will join steemit and will want to buy steem to get steempower which is a vanity asset that more curators will want to own."
Thank you! I have 12-15 altcoins and have picked them for certain reasons. I have read most white papers, but admit that I haven't read them all.
