For the time being I chose Ethereum, because ethereum prices are currently quite cheap compared to the last few months. So I bought Ethereum and planned to hold it for a long time.

there are a lot of fraud projects behind the ICO that are going on right now, but we will find it very difficult to distinguish them because we have to do good analysis and experience.

Here's what I found.

 Strategy "half-Life Points".

If during distribution we notice that:
- - You have been inactive for more than 6 days then you lose 1/3 points and thus lose 1/3 ALT s of tokens in the current distribution.
- You have been inactive for more than 10 days then you lose 1/2 points and thus lose 1/2 ALT tokens.
- - You have been inactive for more than 16 days, then you lose 2/3 points and thus lose 2/3 ALT s tokens.
- You have been inactive for more than 20 days, then you lose 3/4 points and thus lose 3/4 ALT tokens.
- You have been inactive for more than 30 days, then you lose 80% of points and thus get 20% of ALTS tokens.

wow thank you, I just found out about this, maybe there are many other important information that I have missed.
I will search more about this and try to stay active.

I am also a new member here, but after reading the post that you wrote I just want to answer that there are no best coins and always a good place to invest. Each coin has its own fun and has a price that is always changing, so that we must be able to do research to be able to choose coins to invest and adjust to market conditions that are happening.
