No, I dont have, because I didn't pay much attention to altcoins.  I'm sticking to Bitcoin investment.

So you follow the steps of Craig Wright instead of Elon Musk? (both coin promoters)
That's why I don't like altcoins, it's pure hype when big names promote them and create a buzz in the community.
Look at Dogecoin, which has been heavily influenced by Elon Musk's active promotion, while BCH's relative stagnation can be partly attributed to the absence of a high-profile promoter with high influence like Musk.
