I would start by saying that my advice is not to listen to anybody's advice about your portfolio Do what you think is the best, studying the projects and their future applications.

It seems to me a well-balanced portfolio, I like that you own the coin based on DAG (like Iota, OysterPearl, Nano) because they are, in my opinion, one of the future technology, the one that will finally find application in everyday life.

About Vechain, I like that they already have the exclusivity for experimentation in an entire region of China. It can go up a lot.

But I do not like the last 7 coins you have in the portfolio, I would sell all of them and just holding ETH, which can still give a lot in terms of performance.
