I spent all money I had to bought some small percentages of BTC, XLM, XRP, ETH, and NXT at the price around USD 12,5k at the time, upon suggestions of my friends who was get in cryptocurrency earlier. They assumed that btc cs would never fell beneath USD 11k. As a newbie, I followed their suggestions. Since then the prices were fell deeper and deeper. If only I knew that the price will be around at the price on recent days, I won't b rushed to spent all my money to bought them, so I could do better investment nowadays where the prices are more sexy. 
I learn lot things since then. And those things lead me here, to learn and study from true masters of cryptocurrencies. Respect!
