I might be the same as you have no experience in the crypto world but from the info I got and try how to buy it as follows:
First if you want to buy altcoin then you have to have bitcoin or eth You can buy altcoins on exchanges like bittrex, poloniex, yobit. Etc. there are many decks depending on the country you are on the floor that I see in America and Japan are two countries with many floors trade that you don't know in both countries. For trading coins, you have to search for youtube trading videos that have lots of people talking about it but you have to make your own decision not to follow the people you have to learn from the start if you are a first Newbie learning how to manage your capital before you make a profit from trading coins and then learn how to see the way ... first you have to try to trade with a little money to avoid you will lose money if you save everything. Good luck
Thank you very much for the information you provided, this information is very much needed for me to buy coins in the right way, because I have never and have no experience in buying and selling coins, and this information is very useful for me to buy as many coins as possible for my investment in the long run or in the short term.
