No it's not practical.Having a market cap of about 1,5 trillion $ is clearly not realistic,not in the near future anyways.My guess is,after 2018,the bad year that Bitcoin faced the price will from now one rise slowly but surely,building up back the lost trust of investors slowly.
Exactly why it won't be able to raise so quickly. When the market cap of bitcoin was in the hundreds of thousands or millions, a tenfold jump was nothing. But now, there would have to be a ton of money dumped into it for it to rise at that rate.
It all depends on the fundamentals. You can see that TA doesn't matter when the fundamentals are rushing in. This recent dump right after the ETF got delayed, even though the price was forming a bull flag on the charts serves as a proof. So whether we will go to ATH this year cannot be read from the charts. It would seem unlikely looking only at TA, because 8 months of bear market don't turn into an ATH right away, but a big news could change it. For instance if we got all ETFs approved and on top of that had a major retailer accept BTC directly 20k would break in a month.
ETF's might cause some money to come in, but not to the tune of several billion dollars. They're just not that appealing. And there's already been a major move by Starbucks and a few other giants, but nothing happened. Bitcoin is establishing itself in the market. It's carving out a comfortable resting area.
