Its amazing some investors never took their profits and ran last run but are still in this complaining..if its all or none then stop the bitching and get off this bull.During a bullride there's moments of complete confidence to complete fear but if you go the distance you can be a champ.If you want off this bull then step off and walk away.It's the ever dangling carrot any investment has so check your tolerance for risk to reward before investing.
I had a moonshot oil stock I dove in and out of recently ..had I rode the bull up till today I'd be up 35x instead of 4x..my 4x could be 15-20 x more if I go the distance .Risk/reward

So if you like less risk ..take profits..more reward then hang tight
