The main question is what price BTC needs to reach for alt to start facing some upward price pressures again.
I say about $600+. What do you think?
Now that is a good speculation thread, to be honest I vaguely recall that altcoins had an ideal ratio to Bitcoin that they keep, the problem is that besides Litecoin which had a fairly solid baseline the rest of those altcoins have never really experienced a Bitcoin rally and therefore have no known floors yet, I presume that the next best estimate is to value them by market cap range lacking the historical data and extrapolate from it a roughly known Bitcoin price.
My answer is unknown needs more data and research on my part atm .
