The risk is certainly high.
The risk is high - this is when you invest not in 100 projects, but in 1, there is diversification here, so I don’t think that this portfolio is high risk, especially considering portfolios consisting of ICO projects and retrodrops, where scam risks are minimal, because the price entry into the project is extremely low.
But since the portfolio is designed for medium term or for a few years, there's probably not much pressure to keep yourself abreast of each project's development.
The portfolio is long-term, designed for ~3 years. I do not follow the development of altcoin projects at all, only the charts.
I'd be interested to look back to this portfolio in 2025 and see how this pans out. My own experience tells me that in a portfolio full of altcoins, you'd be lucky enough to still have half of it retaining some worth by the time you want to liquidate them years later.
But perhaps with these hundred different altcoins, many taken from top 400, small cap and testnet projects, and even ICO\IDO\IEO, it is probably enough that a handful made it big time for the entire portfolio to register net positive.
Half for this portfolio is a lot. No more than 20% of the portfolio is pledged for unprofitability and death of altcoins.
