Of course there is, but one must make a judgement based on timing and prospects. I’ve personally made more on KBLB than any other stock I’ve ever invested in (circa 1300% to date) so not quite as good as you managed, but still, life changing for me.
It’s clearly not a scam, and I think you know that, sure there have been endless delays, but at some point (in 2021) we’re finally going to see substantial production and sales. And I plan on having some money on the table when that happens.
