I bought a ton of Bitshares at 6000 and now it is down to 5000ish. I feel like I could have bought around 15% more if I waited 1 extra day Any advice?
Will the price matter in a few years?
Should I sell now to buy back lower?
Before selling I would ask myself: "Am in this for the long run, or am I just trying to make a few bucks?"
No matter your answer to that question, you'll realize that selling would mean accepting an immediate loss, without any guarantee you can make a profit later on.
So, guaranteed loss, without knowing you can make up later. Not selling would mean no loss, at least until you sell. If you're unsure and don't like volatility, why did you invest in crypto in the first place? But in any case, nothing prevents you from selling as soon as it reaches 6000 satoshi again, cash out and invest in government bonds. This way you'll earn a guaranteed interest rate, and you'll probably sleep better.
EDIT: Even better, buy bitUSD with your BTSX, you'll get a better return than with government bonds!
