There's nothing wrong to be bullish but sometimes we should not expect to much because it will hurt us big time if our expectation didnt happen. The market is unpredicted, many things unexpected can occur thus lets just hope for the best and have our own analysis if there's a basis for our speculation.
Of course predictions and analysis are only the basis for us to invest in Crypto, of course, because our traders don't know what big waves will be put into what coins and therefore we are better equipped to continue to hold some important coins if it is true that a bullish wave will occur this year.
