Dont Buy BTC Expensive, Wait. Whale want to sell you Expensive BTC now, wait and buy BTC cheaper.
I am still pretty sure we are not going down lower than the current levels but not before we see another short term uptrend in some couple of days and see some rally in the altcoin market.
I would be buying some cheap altcoins now though, to increase my bitcoin stash for the long wait while holding to see the market go down lower because I have the utmost feeling we are not done yet but one thing is whether holding or waiting to buy lower, no one will regret doing so.
