It will affect other countries if US decides to put strict regulation. More strict regulation means more restriction "free movement" between US and rest of the world. Hence, others might try to avoid anything related to crypto currencies that is associated with the US. Or your governments might also follow the same move.

You can't. As long as you aren't involved with fiat currency, there is nothing they can do. But, if you convert them to fiat anytime, you will be subject to a tax. This also involves making purchases through vendors that don't do direct "P2P" transactions. Lets say a site uses coingate to accept bitcoin as payment method. Now when you purchase anything from that site, you pay coingate to convert your coins to fiat and pay the merchant. Hence you have created a taxable event. Laws differ from country to country. Know your laws.

By few more bitcoins being available in the future, you meant that more bitcoins are going to be mined in the future, right? Yeah, that is true but it is not like there is going to be infinite supply. And don't forget, the amount of coins that can be mined are also halved every four years, so the supply is also declined as time passes.
If "you" think this is a bubble, then don't invest. If I were you thinking it is a bubble, i would never invest anything that i wouldn't be able to afford. But, if I were planning for long term investment, then I would invest significant amount since I know in the long run the price will increase. Many medium to large scale companies are also doing this!

If for some reason SEC decides to drop the lawsuit or there is a settlement between them, then yeah, everything might go back to normal. But if SEC decides to go forward with the lawsuit and Ripple tries to fight it back, I am sure it will take months, if not years for the battle to end.
Even if the lawsuit is dropped or they win the lawsuit, the prices might not go back to where it was as people might have already lost confidence on them. So, if you are deciding to go all in before the lawsuit ends hoping that Ripple will win and the price might rise back, think again.
Lol.

For your first case, are you satisfied with your profit? Have you taken enough risk and now want to just reap profits without risking anything? Then go ahead. Take off your initial capital and invest rest of your profits. Choose coins that are well established and forget about them. Check them back after years and enjoy whatever you made!

For your second case, can you afford to lose? If you can, then forget about your "first option" and just invest. In both case, if you invest in well known coins, in the long run you will make profit!

I have seen worse. The thing is, they don't do proof reading. They make build a website real quick. Not one but 10 to 20 of those sites of different themes/service/features at once and then tries to scam unsuspecting users. As far as I know people even sell those programming  codes and designs so that others can also set up their own scam websites.
If you visit a website, find it fishy and see a lot of language errors, then either they aren't native speaker of those site or they are bland scammers.
Those "top notch" scammers that you are talking about still exists. Probably earning peoples trust before screwing them up.

1. You can't shutdown something that is decentralized. Can you shutdown p2p torrents? Look how many times the government failed trying to stop piracy through p2p decentralized torrenting. All they can do is regulated the usage of crypto currencies. Strict policies are being imposed which might indirectly make using crypto currencies legally somewhat centralized.

2. Sadly, this is still true. Only few stores and online shops accept crypto currencies but the adoption is expanding faster than people expected!

How and why? People has been making insane predictions the last few weeks without any solid factual backups. I have seen people making prediction that within few months, if there isn't any resistance, the price will exceed $200k USD. But, based on what? Are they trying to spread fomo among people?
Even the altcoin predictions that you have done over here needs explanation. Lower market cap coins are profitable in what sense? Never heard of Miota and Ark though. Even bitcoin reached $60k, it is going to take more than few months since we are yet to see market corrections. I am hearing about this new regulation coming from FinCEN where we will have to register and declare our private wallets if we want to use exchanges. Not sure how this is going to affect the market.

I doubt you would be able to sell 50,000 bitcoins at once! That would be insane for a "normal" user to do this. You will probably trigger a security alarm and your account might get flagged and locked. If you want to use an exchange, maybe contact a reliable exchange first. Let them know how many coins you are going to convert. Give them all the details and ask for suggestions. I am sure they will let you know what sort of documents and other things you might need to prove your ownership and to see if the coins have originated from a legit source with all taxes paid. Again, they probably won't be able to convert all of your 50,000 bitcoins. You might have to contact different exchanges.

Who knows. You might well be waiting for the price to go down to 20,000 USD, but when is that going to happen? What if it never happens? People have been thinking the same way for a very long time. When the price rose to $2,000 back then, people probably waited for the price to drop to $200 (not real, but I am making assumptions). But that never happened. So now they regret. The same might happen to you. You well be waiting for the price to drop to $20,000 USD but that might never happen.  What if the new low of bitcoin is $30,000? Like others said, you don't want to wait for the price to go below $30k USD.

Due to this lawsuit, the price has fallen significantly. People are now buying at this low price. They believe that if somehow ripple manages to defend themselves, the price of XRP might skyrocket. So they are taking the chances. I would say really risky, but yeah without risk there are no profits.
What if even after defending themselves, "most" people loses confident and the price no longer goes up? Or it might be the opposite, who knows. So, yeah they are risking it to get the maximum profit!

If a site blocks a players account because he is "winning" bets, then you shouldn't play on that casino. As long as you are not exploiting any glitch/bug of the casino, they have no right to close your account. They might temporary keep your account on hold, but will be bound to release it. And as far as I am aware, there is no casino that prohibits using scripts. So still makes no sense of him to sell his scripts.

Sure, if you can afford now, then buy. As long as you are planning to hold for long term, then go ahead, there is nothing to hesitate. By long term, I mean if you are planning to hold for several years. Look at the charts. The price is increasing on average as years passes. So if you invest now, in the long run, you will make profit. Just don't, if you can't afford loss and thinking of making some quick profit.
Use your own instinct and your own ability to take decisions. The more you hear from people, the more confused you will be especially when it comes to investing in crypto currencies.

Don't go looking for "free" ethereum. No one is every going to give you free coins. Those that do, actually make you do tasks. Like faucets make you watch advertisement and pay you dusts that won't even cover the transaction fee.
What you can do is:
1. Got a skill? Try selling it. You can start by heading to the service section and offer your service.
2. Try joining various contests that are hosted over here by different platforms.
3. You can start blogging. Write interesting stuffs to generate decent traffic. Once you are have an audience, you can earn from ad revenues. Coinzilla may help you in this case to generate revenue in crypto currencies.

Don't listen to others suggesting you to join bounty programs. Waste of time. 90% of those are scams.

1. As long as you can AFFORD to lose it. If i have $10,000 it doesn't mean I should buy $10,000 worth of bitcoin. I would if I can afford to.
2. Or you could wait for correction or fall. Some events might trigger the price to drop. If you are aware of such events that is about to take place, then wait.
3. Not sure what does this even mean.
4. huh?
5. You are now starting to make no sense.
6. Gibberish.

You taught him everything, but you forgot to teach him about security :/. That's the first thing he should know before starting to invest or use crypto currencies. And that was stupid of him to "send someone coins" to trade on behalf of him. It's like begging them to scam you. I am sure he was scammed a lot of time even when using fiat currency. Ask him if he thinks fiat currency is shit.
Good thing he realized his mistake and admitted that he was wrong over here. There are people out there who would be stubborn and arrogant after getting scammed. They would keep on blaming crypto currencies.

See. You were wrong. I know you didn't say it was going to dump, but you kinda did try to scare other by reminding them what happened in the past years. Fortunately nothing happened. The 2017 didn't repeat and the sharp drop of March didn't happen. The price did drop a for few days, but managed to hold up and is now rising once again.
Make posts like this will just spread fear and doubt in peoples mind. This post might have refrained people from investing when the price dropped to $30k and miss all the opportunities. :/
Yeah, it is risky. But can't afford to risk, don't enter the market!

You probably got luck with your script. In the long run, you WILL lose your money unless you some how managed to  magically beat the house edge which is impossible.
I find it funny because will you sell something that can "defy all odds" and give you profits? Can't you just run the script forever and enjoy free money?
And no one is going  to use your bots. Might be infected, who knows.

It isn't all scam, but depends on who you buy from and if it will actually arrive or not. Like others said, buy from official sellers. You might also get off branded or generic GPUs for sale, but the build quality might be shit. Make sure you read the specs of the cards.
I remember Linus making a video about GPUs ordered from Aliexpress. You should watch it. https://youtu.be/PUIxyLRnzDc

This article and news has been circulating for days. Kinda feels like this is spreading negativity around the crypto space. But the comments are damn hilarious. There were people saying they knew this will happen. There were others saying its a ponzie scheme controlled by the "kingpins". They make you lose "passwords" so that you can't access the coins anymore after you paid them to buy bitcoin. One guy even asked why can't they "call bitcoin helpline" for resetting their account. Lmao! Shows how much people are unaware about bitcoin and the technology behind it.
Speculation. Impossible to accurately find how many lost coins are there. Imagine how many wallets carry dust amount of coins.

If I remember correctly, the site he represents offers plastic cards too. I am sure those cards can be used in ATM for withdrawing cash. I was looking at their trustpilot rating and there were people calling them scams (hidden charges and whatever. Didn't bother reading everything) and others accusing them of posting fake reviews.
I used to use their cards before like maybe 3/4 years ago and all of a sudden they told me that they were no longer able to provide credit card services and had to empty may card as soon as possible. Almost forgot about them and until one day I received an email from them that they are resuming their service. Logged in and saw that they still don't offer their service to the US and for rest of the world was coming soon.
