Hi I am new user in bitcointalk.org and I want to buy some altcoin. I have no experience about trading. Please share your experience.
You can actually buy altcoin from exchange sites like binance, kucoin, poloniex, bittrex etc. You just have to make a personal account to deposit a currency/cryptocurrency which will be used to buy your desired altcoin. Of course if the currency you have should be supported/tradable to the coins you want.
For example you want to buy ETH, then you should have USD or BTC since they are tradable to ETH in most exchanges.
Also, the exchange site you are in should be considered. Many exchange platform do not support other coins.
For example, you can not buy KCS in binance exchange or buy BNB in Kucoin.
That's all I know I hope it helps. Feel free to correct me I am still learning anyway.
