Anything about stocks, and the economy, and how to gamble with option on it. "Hodl", and "to the moon" meme are welcome, as long it is not another conspiracy about the short squeeze of all time, or whatever bullshit born from "that" stock
Warning: Gambling is an addiction, consult about it if you are concerned.

I still firmly believe alternatives for lithium batteries will be the best step in sustainable energy. Currently there's a huge surplus of green energy like wind and solar that has nowhere to go. Lithium has its downsides (cobalt and lithium mines, graphene) so something new and more dense is needed. I read sometimes, a bit buried away, about solid state batteries and stuff like sulfur natrium combinations. I bought BASF (the building blocks), CATL (the research) and the L&C battery tech ETF. Only CATL has really been profitable so far. Especially when the straight of Hormuz closed it jumped up.
