With btc the KISS principle has always worked out pretty fucking well, and will continue to do so as far as I can see.
Buy bitcoin. Only sell if you absolutely have to. Like a loved one needs a kidney, or the bank is coming to repossess your house or some shit. In bear markets don't look at the price. Sometimes for years. Chill the fuck out. Don't think you are smarter than you really are, sure as fuck don't think you are smarter than the chaos that is bitcoin price movements.
Buy bitcoin. Don't stress. Don't sell. Don't be greedystupid.
I think all the bear trolling and attempts at scamming around Bitcoin is super weird. Go to any Precious Metals web forum and you never see bugs talking about TA charts, elliott waves, when to buy, when to sell, blah blah blah. Just "buy PMs when you like, and buy as close to spot as possible". They are just happy to be able to buy and hold, never sell unless they have to. No talk about trying to get super rich with PMs. And instead of panicking when the PMs price dips crazy, they instead talk about "backing up the truck".
More people coming into Bitcoin need to think this way.
