I'm still pissed off at my friend who bought 3.5 k LSK in January (~0.15 USD/LSK) and didn't tell me about it at that time
Don't be mad, if you open your eyes and use your mind you can and will make returns even higher than that, that's about 33X ROI compared to todays' price. Not to say that's a bad return it's awesome of course but a lot of money is made in this space if you can spot the good ones early on.
It's not your friends duty to tell you about investment opportunities. I've been fortunate to have made outrageous returns and never told anyone about this except posting on this forum with my alt account, in fact it's not smart to tell anyone about your investments and their returns as this usually backfires later on in 9/10 cases
