Today price is best example of market confidence in BTC. In 24h bitcoin dipped and went back with the price, nothing really happened, except it take over 54% of market cap and slaughter all altcoins!
Yes that was a very good strategy, taking advantage of the current situation in the market by investing a huge amount is the best thing to do to earn more profit before the market price pump up again.
I think that's about to change when the market recovers. People probably are a bit weary of holding and dealing with alts since they've dropped quite significantly while btc proved more resilient.
