Couple of days ago we have seen significant move in a day but again with the correction of BTC price, each the coin has lost a huge value. I think we are very far from a altcoin bull run, may be later this year we can see that.
There is no guarantee that by the end of 2019 it will bring altcoin back to the moon. But at least I'd rather wait for 2020 where many people expect more. At present the price of bitcoin is $ 8000 and continues to fluctuate. Fundamental factors will be able to make bitcoin rise again above $ 10K - $ 20K.
The comeback of altcoin will be difficult it will only happen if BTC will start the bull run and other altcoin will follow but not all of them there still altcoin that no more hope even BTC bull run start .
agree with you to some point. btc surely must start it's bull run first, but while btc is mooning, i don't think alts will follow the btc. on that time btc did it's ATH, altcoins jumped just after btc saw its maximum.
so from my view, it won't be at the same time, we need a btc bull run first, then btc and fiat will flow into alts.
