There are a lot of blockchain projects this year with great potential in terms of concept and development direction/plan. It's always good to do your due diligence first when finding out the details of any blockchain project, and there's no harm in joining airdrop and bounty campaigns to find out what the project is about and how interactive the admins/project's team is are on their social media channels if any. I've been looking at BCART (BlockCart) tokens and joined their airdrop/bounty campaigns recently - and it's always a good sign to see the admins clearing spam and bots on the chat and also being responsive. They're still in the midst of developing the product, but blockchain in e-commerce, customer service and online shopping as well is interesting. What other factors do you guys look at when it comes to determining if alt. blockchain projects are safe?
