In 2017, a friend of mine bought thousands of nano with 1 btc. If I remember correctly nano was $0.45 in those days. About 2 months later, when the price of nano exceeded $20, my friend had entered with 1 btc ended with 32 btc this adventure. I was really impressed by this success and I think the biggest altcoin portfolio I've ever seen was that portfolio.
This is a very good story of how 1 Bitcoin was eventually rolled up to become 32 Bitcoin in terms of value with the help of the Nano coin. The year was, of course, 2017 which was the time when many of the existing coins and tokens made their colorful and exciting ATH. No wonder many of those who invested at the early part of 2017 made a killing just months after when the bull run got into its course.
As for a portfolio, I know of a friend in social media who got almost $200,000 in Ethereum but unfortunately after that the Eth went into dips and now I think his portfolio is just around $30,000 if I am not mistaken (actually he sold some of his coin last year, that is why it declined a lot). As for me, I only have a minuscule amount of Bitcoin, Ethereum and some shitcoins too (from bounties, of course) and total value can be negligible but I am planning to add more this year in preparation for the halving next year and expected ensuing bull run.
