Shareholders' Equity and Share-based Payments [Text Block] | Note 11 – Stock Options and Warrants Equity Incentive Plans In October 2019, we adopted our 2019 Stock Incentive Plan (the "2019 Plan"). Under the 2019 Plan, our Board of Directors is authorized to grant both incentive and non-statutory stock options to purchase common stock and restricted stock awards to our employees, directors, and consultants. The 2019 Plan provides for the issuance of 16,000,000 shares. Options generally have a life of 3 to 10 years and exercise price equal to or greater than the fair market value of the Common Stock as determined by the Board of Directors. Vesting for employees typically occurs over a three-year period or based on performance objective. The following table sets forth the activity of the options to purchase common stock under the 2019 Plan. The prices represent the closing price of our Common Stock on the OTCQB Market on the respective dates.

The fair value of each option granted is estimated as of the grant date using the Black-Scholes option pricing model with the following assumptions: Three Months ended March 31, 2020 2019 Risk-free interest rate range 0.48 to 1.65 % -% Expected life of option-years 5.20 to 5.77 - Expected stock price volatility 110.8 to 128.0 % - % Expected dividend yield - % - % The risk-free interest rate is based on U.S. Treasury interest rates, the terms of which are consistent with the expected life of the stock options. Expected volatility is based upon the average historical volatility of our common stock over the period commensurate with the expected term of the related instrument. The expected life and estimated post-employment termination behavior is based upon historical experience of homogeneous groups, executives and non-executes, within our company. We do not currently pay dividends on our common stock nor do we expect to in the foreseeable future.

We estimate the fair value of options at the grant date using the Black-Scholes model. For all stock options granted through December 31, 2019, the weighted average remaining service period is 3.6 years. We recognized $381,475 in stock-based compensation expense, which is recorded in selling, general and administrative expenses on the consolidated statement of operations for the three months ended March 31, 2020 and 2019. Unamortized stock option expense at March 31, 2020 that will be amortized over the weighted-average remaining service period totaled $1,794,251. Restricted Stock and Restricted Stock Units In the three months ended March 31, 2020, we issued 1,398,224 of restricted stock, to certain employees and directors. Shares issued to employees and directors vest over a time frame from immediate to 1 year. In the three months ended March 31, 2020, 1,157,889 shares of restricted stock vested.
