Honestly I'm again alive with what I am seeing now, bitcoin already trading at $8,000 after being down for months and stayed at $6K+ for awhile.
With the halving is happening in 126 days from now, if that bullish start we have now will continue, this should create a great price nearing the event.

I'm quite too optimistic but this is how people react when they saw bitcoin is moving bullish.
let's check this schedule again and again (https://www.bitcoinblockhalf.com/)

Yeah, this year crypto will experience a pump because it is rising more than before. I can see in crypto New investors are taking part and I hope to get a new market pump. Right now it’s not yet fully pumped but with the passage of time, I think the market will increase to a huge level since long people were waiting for it.

It's really hard to trade a lot with the prices going down.
You really need to know the market and i think know something of economics/crypto to make a profit.

I like to Research a Coin/token and then just hold it for the longterm.
Made the mistake once to sell it to early (before the rise to $20k) and buy a new pc with my earnings.
Well that pc would be like 60k$ at the highest price.

So yeh the best would be to have a longterm price goal and sell it, and then maybe when the price goes down again you can rebuy.
And keep or reinvest the profits.

People were bored with the current socio-economic order. They are constantly forced to consume. Bitcoin can destroy this scheme. Of course it won't be easy. Maybe it won't build a better system, but things will change. Bitcoin offers a more transparent and accessible world.

Nothing is confirmed yet that's all speculations and nothing more no one really knows if bitcoin will go down to that level, but if bitcoin doesn't manage to close its weekly candle in or above the key support then we should expect a bearish movement to occur most likely and the price could dump all the way up to the $5000 levels. It will also act as an opportunity to buy in the lows, however. I wish it drops that much so that i could pick up some cheap corn.

It is very possible.  Bitcoin goes up to $14k last year without any major event being announced so why would it not reach $15k due to halving.  We all know that halving often gives the market a great hype and history had shown that BTC price goes up before and after the halving event.  Investors think that due to halving of the block reward, Bitcoin became more scarce and that means more demand and less supply.  With this in mind FOMO may possibly break out pushing the price of BTC higher.

It's just a dream at this point.

Besides, why would a bitcoin backed USD make any sense? Why not just use bitcoin itself? And would incentive would the central banks around the world to ever reform their currency in such a way? They obviously don't want to let go of the control that they hold over monetary policy.

A tokenized US dollar could be possible but certainly not with the backing of BTC. You also have to take into account the potential for fractional reserve to be instated.

If crypto vanishes then there will be some new invention and we all will be busy with that.
There are very few chances that such a huge market will vanish in future. Most important thing is that there are millions of people in cryptocurrency sphere and most of them are of young age. They are the one who will carry forward the future of crypto.

I was trading from work in 2017. I was basically trading at home all day and at work I was watching price most of the times, but there were so many opportunities and if I didn't trade I would have to skip going to work.
Imagine going home and find out that Roger Ver started shilling Bcash and basically your investment went down 30% and Bcash up 500%. I'd have to leave work completely if I didn't trade there. I basically doubled my btc holdings at that time after two days trading. I think I either had day off the next day or it was weekend. Basically I was asleep for more than 48 hours. I traded all of 2017 from work and noone said anything as there was no regulation against it and I was doing my job as usual.

Exactly, let's manager our fund wisely and our time, make sure that we have listed everything that we are trading, and if possible write down the TA that you used on it, so you can check and analyze more once your TA has not been good, or the price moved on different direction, so make sure that know and better to familiarize trading  and different strategies.

In my own personal opinion, my preparations this upcoming year of 2020 is I would hold all of my bitcoin and altcoin until all of it's prices increases, so I could get back all of my losses from the year of 2018, which we experience I huge losses from bitcoin after it increased it's price up to $20,000, that is why holding it is the best option for me to have a good profit.

There are some platforms out there that let you 'make your own bot', quite useful without having to design the whole thing from scratch

I sort of wonder about this because of that Jeopardy guy James Holzhauer and his incredible ability of consuming an unlimited amount of information and his recall ability. Add to that superior knowledge and common sense and a person like that would be great in speculating. 2nd to known.
