When you are suggesting something which is not familiar for most people here, it would be a good practice to include its ANN topic or website so that we would evaluate your suggestions without needing google. Honestly I am not familiar with all 3 projects you are mentioning here, anyway thanks for your list.
1. BAANX: Baanx is secure, custodial wallet platform and bridging gap between fiat and crypto. Already have ios, android app and launched their debit card in 30 countries.
I am sure they must need to face heavy competitions in their markets as there are many similar giants are already in action and among them crypto.com seems the lead as in bittrex they are always having top volume in every 24 hours in BTC markets as far I have seen.
2. AIMEDIS: Decentralized blockchain backed ehealth ecosystem, offers more than health, in anyplace, anytime. They are getting ready to launch their own platform
I have invested on MTC project as it is dealing with healthcare industry. It once performed well but not in current times. Healthcare projects are always competitive and known for good returns over the time. let me check this AIMEDIS, whether they got anything to convince.
3. Tachyon: Decentralized blockchain based internet protocol that wants to create secure and privacy internet. They promise faster, secure and also pay for staking ipx into the wallet
Have seen many like this, I am not sure what kind of innovations they could bring in IP things. Not my cop of tea after plenty of bad experiences with same sector based projects.
