Blockfolio is my favorite portfolio app and reasons are clearly evident. It has many more APIs and supports much more exchanges and cryptocurrencies than any other such software or app. On the same hand, having all data on your mobile with all recent up/downs is much more convenient than accessing desktop based software for them. All crypto enthusiasts who invest in coins do keep their tracks on such apps as it is very helpful is lining all the movement of your funds and having better management of them.
how is all the famous coinmarketcap?I think it's best to check every coin! there is all the information available!
You can't maintain personal portfolio on all the famous CoinMarketCap.
Yes, you are right! This is probably one of the only disadvantages of this site. But agree with me, you will not find more accurate information about the coins anywhere in the market, the year of foundation, charts, and so on.
