First, through the Coin Market Cap website, you can search for any currency and then follow the numbered steps here.

1. The first image is an example of the currency $WIF that we want to examine its details to ensure before purchasing any currency.

2. Click on the Chain Explorers section

3. Click on SolScan or EtherScan

4. Click on the Holders section to know the distribution percentages of this currency across different wallets. If we find that one wallet holds most of the currency, that is the first negative sign.

5. Click on Analytics

We will learn about the volume of the currency, in addition to the number of wallets that hold and trade this currency.

There is another important site that provides you with additional information which I shared here before called Skynet.Certik
