Hello guys!, In your years of experience investing in crypto, aware of its volatility, what coin or token maybe you regret selling the most? Maybe today when you look at the market you cry because maybe the coin you sell last month is life-changing in price already. 
Oh man, why do rip open old wounds? 
My hardest regret is Stratis, I bought into the ico, then bought more when it dumped and sold after 3x. Went x100 some weeks later...
