Bitcoin is so vulnerable to a 51% attack. Ghash supposedly has 45% of hashing power, but what about the Unknown category? I am not willing to risk all my bitcoins because of a 51% attack.. I am converting to litecoin, which is being pumped now btw..
Thats not a pump, thats a dead cat bounce. The last dying breath of a dying coin and it's already run out of steam.
Have a look at Doge's last couple of months - same pattern. Long slow drift down with sporadic bounces along the way as some hopeful speculator thinks they've "caught the bottom" when in fact they're just attaching themselves to a sinking ship.
I wouldn't put my money in LTC for anything right now - it's in terminal decline.
