Sonm price is stating to pump because it was just added to the Binance exchange. They added it because the roadmap is solid and is almost certain to rise as they get closer to releasing a usable product. At the same time the BNB binance coin is also rising so a good time to grab a bit of both
I sold BNB at 80 cents. Feel so fucking stupid now.
Don't sell all at once
I sell half when I think it hit its highs, then half of the remaining when it goes higher/lower by x%, and the rest of it I usually hold.
And for the record I havent sold a single SONM and don't plan on it for a very long time!
