ALGA symbol use to be NVAE.. NVAE was poorly run company (if you want to call it that) and ALGA did a reverse merger into NVAE.. since then, the new management has done everything they said they would..
i'd suggest you do some homework and determine if this is a company you want to invest in. there's some concerns surrounding this company and some think it's a typical algae scam. just be thorough and make your own decision..
