The nice thing with Bitcoin is, it follows the rules you can find in all trading chart analysis, but the greatest difference is, that Bitcoin has nothing it can relate to, but it self :-)
Resistance becoming support and vice versa, trading channels, symbolic levels, symbolic dates. All of these can be found in Bitcoin's patterns as it progresses, in it's purest forms, because for the moment Bitcoin, except for the other 'alt-coins' is only related to it self and not to what goes on in eur or usd or gbp etc.
