If the flat phase happens this summer a bull market is likely at the end of 2018 and early 2019, and if big fundamental changes happen in the crypto-space (that could fasten crypto-adoption for example: fiat pairs on major exchanges and the removal of Bitcoin pairs, fiat gateways through tokenization, crypto-exchanges for tokenized traditional assets etc...) a second bubble is likely. For now the token mania has passed but we're still in a very irrational market, where many projects are launch while there is no demand: EOS, LISK and the hundreds of other cash-grab blockchain projects which bring little to no innovation yet billions in speculative investments. This shows that crypto is still in its very infancy.
As for Bitcoin, if nothing changes the bear market is likely to continue for several years:
Without changes in the fundamentals, Bitcoin won't stop losing value. It can't do many things and it does these things poorly (Bitcoin several years earlier was more widely used as a currency than it is now). What's keeping Bitcoin from going down is its network adoption, which is why its value will decrease at a slow but steady rate unless things change drastically.
