I challenge you to test your mental mindset to its limits while holding crypto currency long term. I've made a 5 figures bet into crypto currency (my current choice is litecoin) and predict $500,000 USD by next bitcoin bull run PEAK.
Time will tell how right I am. The current range for next peak appears to be $250k to $1 million via John MCcafe. I may decide to cash out earlier than 500k depending on fundamentals in future. So we will see what happens.
