If it's your first time here in the bitcoin world and you want to experience earning here in this field industry, I suggest to you that you dedicate it to Bitcoin, because if you try to start it now, I doubt that you will not experience that you are not earning here on Bitcoin that you will hold until the bull run comes.

Now, if you feel that you want to invest in other cryptocurrencies besides Bitcoin, it is better that you base cryptocurrencies only on the top 20 so that you can be sure that you will get a profit from them.https://coinmarketcap.com/
