Biggest regret? Waiting to get in! I first became aware of Bitcoin when it was floating around $10...and I didn't bother to force myself to get into it at that time. That's my biggest mistake.
Stop waiting, get in there!
Any specific questions?
Thanks for your response and advice, I have just started to invest in bitcoin and looking at others. I am wondering if I'm spreading myself too thin. I've purchased several different coins and am just wondering how often you buy and how much you invest?
