I just started yesterday....... it took me like 10 days to know as much information as i could to start investing in crypto. Started from trying to understand Bitcoin, Blockchains, Alt Coins, ICOs,

I am so new to crypto, and had an issue that made me a bit worried on my second day of ALTCoins. I started to discover the market with 1kUSD and my only way was CEX.IO. Yesterday was ok, today was ok,
