TWA & Walrus, I continue to have concerns regarding Coretec's business plan. Patent is at the very top of the concerns list. Next is financials.How is Coretec going to pay this chemical company supplier for the CHS batches? How is Coretec going to survive financially once the CHS batches are shipped out to the customers. However, I'm excited that Coretec is making progress with the chemical company supplier. At this point, I'm going to wait & see what happens in 2020. I've made back my invested money so far. I'm waiting for the announcement of the chemical company supplier partnership. Then I'll decide whether or not to sell my shares.I'm hoping that Coretec can successfully market CHS. That's my prayer for all invested in Coretec....
