Investing since 82. Felt the pain of the 87 and 00 crashes. All fiat money is subject to devaluation. Most trading is now done by HFT-bots trading among each other.
Over 25 years experience as a networking geek. Now am a network security geek.
I'm new, but learning something everyday.
I like bios/ tech, but they must have fundamentals.
Read everything you can.
P.S. If you try to pick the bottom every time, all you get is sticky fingers.
P.P.S Use stops.
