$ARQQ haven't entered a new name in a while, but I'm liking the combination here. Post-quantum encryption is easily a theme that will get crowded at some point...this stock is very low float and market cap and huge short interest. Yes they are burning cash but they have nearly $40M left to spend, should carry them through another 2 years. They also have exposure across a ton of big tech names which legitimizes what they're doing. Not a huge exposure, only 2,000 shares...if it goes down towards $10 will keep adding up to 10,000 shares total.
