I'm thinking a pre halving attempt to $680 could happen.
i think you mean 480, because we still have some resistance such as 480, 505...
I cannot speak for Dilla; however, I doubt that he was talking about $480 as being some kind of target high price.... hello? Do you see the actual dynamics, here?
There is likely real resistance between about $467 and $475; however, once we get to $480 any remaining resistance is likely to melt away, including any figment of a $505 resistance.
Surely, I consider that it is very feasible and even reasonable that BTC prices could bounce between $430 and $475 for about the next 2 to 3 weeks; however, we know that BTC prices tend to overshoot and to play out in fairly unpredictable ways...
Nonetheless, the odds are looking better and better for up, rather than down. Maybe we can place the odds at 40-45% that we will stay within $430 to $475 for the next three weeks? But once we get above $475... if we do, then probably the odds are above 60% that prices will go above $600 within the next 3 weeks. Yeah, none of us have crystal balls (at least ones that work), yet your describing resistances as $480 and $505 (and even suggesting that those resistances are meaningfully strong) - seem a bit off of the actual current BTC price dynamics.
