You can start by trading on your own and be experience-wise. But the easiest is why not just ask that guy about his predictions and what are the methods he's using for predicting the market and how he reads the charts.
If you also read some of the posts on the speculations, there are technical analysis there where you can absorb and study how they've made it. Learn the basic fundamentals of trading first and its terms.

Hold the bitcoin and if the time comes that you have spare money, that will be great time to invest in altcoins. It's not advisable to spend your bitcoin while the market is dropping, it has lessened the dollar value so that's my advice that just hold it for now.
But if you are pushy and you really want to buy an altcoin with bitcoin, choose ETH.

Don't be so quick to expect that this year bitcoin will get a new ATH. I will not expect something like that as big as this early this year.
As you can see, bitcoin just fell a few hundred dollars and if someone still thinks to sell his alts, now is your time to buy bitcoin.

Wrong section.
Move the thread to Announcements (Altcoins).

Still not.
I like dex but like the majority sentiment, the volume is very low and it can't sustain the traders need. But in all summary, DEXs are good until they become semi-centralized. 
If you know what I mean.

Haha, I added a salt of grain and assuming that for obvious reasons that he's really joking. 

I don't think that there's a need for them to do this even if they have to.
There's no point of making smart contracts just like Ethereum and they should be more focusing somewhere else. I don't like this coin either but if it remains to be one big competitor for other altcoins then they should remain the way they are right now.

Ethereum isn't being affected much with this sudden dip. Being a holder of some altcoins, I'll sell if I think it's no longer needed to have that coin in a way that it's volume doesn't go up or there's no more interest into it.
You have alts to sell or none, keep on buying bitcoin.

You got it right!
A perfect example was with the very known electrum. This wallet is very legit and popular but scammers made a phishing site and fake wallet so those that doesn't know the actual website might land to their website and make it think that the wallet itself is safe.
Those incidents made them think that Electrum isn't safe but in reality, it is safe but they just became a victim of fake wallet and fake website.

IIRC, around 2016 or 2017 there were people that were actually telling this that soon Amazon will accept bitcoins directly. However, it didn't happen but somehow became true but with help of third party providers.
It will make the mass adoption quicker and it's Amazon so whichever cryptocurrency they'll start accepting directly, will hit big. But we don't have to wait for that moment, they're already good with 3rd party that helps bitcoin users to pay them w/ it.

Buying the bottom isn't always like you are expecting. If the chosen coin you have bought the bottom is bitcoin, it's a bonus for you because everybody aims to buy at its lowest.
But if the set of choices you are buying at the bottom are the unwanted altcoins, you're doing the wrong thing.
This is a correct advice. DYOR and before buying, do it with caution if its with altcoins.

Earnbet has ended its campaign as per manager.

Seeing that there are hundreds of cryptocasinos that you have reviewed made me realized that it's already a lot. You're not a casino and my concern here, this is more of a Service announcement and it shouldn't be here although you review casinos.

Be also wary about sim hacks. It's been one of the most trending hacking with huge amounts lately.
$45 Million Worth Of Bitcoin And Bitcoin Cash Allegedly Stolen In A SIM Hack

Most total supply of what? traders? of all coins? Binance is overrated despite it had a hacking incident but they've managed to make themselves mighty by refunding the affected ones.
We're sometimes using some words that making the exchange more beautiful. I also like Binance and I use it, it's undeniable that they are very popular but I think it's an exaggeration if we say they have the 'most supply'.

Monero already has the speculations thread.
[XMR] Monero Speculation.
It's the right place to discuss things related to its price.

I agree that op should remove the BCH halving. It's not even interesting and if there are people who are even talking about it, they are not that much.
We're all up to the BTC only halving.

That will change the situation. Many companies will let their stored bitcoin to flow into the market again and won't be scared of selling it to fund whatever their projects are.
And some the cost will go to the marketing which will be for the bounty hunters and other marketing stuffs that they need to expand the project's viewership.

From this list, I'd like to suggest the first on the list roslinpl but his term wants you to pay upfront for 50% and the other 50% once the signatures are done.
I think that term is the right one but still good luck finding the designer who will agree with your term, malubit.
