I'm not aware of any penny stock companies that have a platform whereby crypto can be bought and sold . Albeit its jn its in its infant stage, but can't be denied the foundation is set bigly with Sardlne powering the platform.
Speaking of which, i saw an issue yesterday and sent a message in the box that was presented to me on the platform and within 5 minutes a Sardine rep contacted me and the issue was cleared up quickly .
Not just a website, it's crypto platform for buying and selling going for less than 2 cents with a company that has zero debt
