You can never be sure, or else everyone would be predicting the future of different markets and everyone would be billionaires. This is just my analysis on Bitcoin and you're free to do what you want with that information.

The 3000 USD level was predicted by analysing the market behaviour of the last big impulses or spikes that occurred in the Bitcoin historical price, and this is also how I predict the pullback that most likely will happen before the next spike to the upside. Well, this and of course some basic understanding how cryptocurrencies works, It's not like regular currencies.
