I entered the crypto market in December 2017, that was pretty bad timing. I was really scared, so I started with only 5% of my liquid funds. Then I saw everyone getting rich, my coins mooning for 500% etc and I was like "Omg, why am I such pu55y? I can go allin now and change my life, it's so easy..." But I was also aware of the fact everything can go bad really fast so I resisted this really big desire. And it paid off. My coins dumped to hell and if I invested 100% of my liquid funds I would be really screwed now. So not being greedy and staying disciplined was the smartest move so far.
