I don't understand

So can we mine or is it a pure POS?
we do not hold mining, the task we undertake a concept that is not used by many other developers, and we provide a pure POS for shareholders lenteracoin 2.5% per month. and keep in mind we provide evidence not promise, we always give our latest updates through our social media, thank you, first there will not be a dump of our coin price
How can you guarantee there will not be a dump of the coin's price? Most coins have a crash in price sooner or later, including bitcoin.
