Here's a good rule of thumb to follow when looking at what to invest:
1. The project must solve a problem(s) that affects lots of people.
2. The use of blockchain and cryptocurrency is essential for the solution to work.
3. There are evidence of a real team behind it (e.g. videos and photos of the team promoting the project, responsive when asked questions).
Absolutely absolutely, these are essential when you want to invest in Altcoin or any ICO. You need to pay attention to the basic rules so that you do not have to make the mistake of investing.
many people lose only because of their own carelessness it is not good to show carelessness because our earning is our entire life, so be very careful and dont invest for those who has no good record or pretty new, one more thing is a lot of people are now there only to scam your money so if you want to have good profit then dont let them take your profit, and do not tell anybody about your earning so that he may not try to scam you.
