with a trezor, even if you wanted, you can never know the private key, nor can any computer or virus or any other person!
a piece of paper or an usb is safe aslong as the entire process of generating your key and writing it down, was done properly. it's simply easier and much more convinient to use trezor, but it also costs.
I wrote some more about this here 

I wrote a guide about using wallets, it can be found here! It's very important when using MyEtherWallet to remember that there's more than one way to be deceived, the service itself is safe but there's plenty of phishers and even DNS hacks, so if possible, try to get a hardware wallet

surprisingly, there's tons of bounty managers with seemingly very low rank, speaking broken english and such. curious how they find the bounties to manage?
but, surely it'd be easier if you have a rank and seem generally knowledgable and then advertise your services here.

to reach a high number of adoption will take years I believe, because most people aren't willing/capable to deal with all the (currently) problematic steps involved in getting crypto, storing it safely, spending it, and to top it off - a mistake is irrevokable. I think there is a long way to go before we find a stable platform. What country could reach 50%? 

in my opinion, there's no point in looking for any other currencies. they aren't as distributed as bitcoin, they aren't as big and they can be attacked, and how would that realistically ever be accepted as a payment medium? even if bitcoin is slower than other alternatives today, bitcoin has and will always remain the most well distributed coin that exists! there is no other coin that can get the same level of distribution, because now everyone "jumps on" the next deal and starts mining/buying early and therefore the distribution is never going to be serious.

it's time to look beyond currencies I believe, blockchain has far more value than being a currency. tons and tons of companies are adopting the technology, not bitcoin-payments.

50,000 people per day is not a bad amount considering that's just one-place, so there's plenty of interest still. I guess people wants to try and catch the next ride!
50,000 = 350,000 per week. december was 500,000 according to previous poster. quite impressive!

I think indeed their economy would collapse, they left the gold standard a long time ago, and the entire world knows that incase US would "fall" economically it'd ripple worldwide so we all pretend it's alright! 

that's a good list, but OP, be careful with whatever you read, especially in any specific subreddits. there's a huge issue with bitcoin/bitcoin cash going on right now, aswell as in general there's alot of shilling from pnd groups so be careful! although it's the same here I guess. everyone's an expert 

I actually struggled to find somewhere to buy bitcoin myself using PayPal a while back, and as earlier poster said, I don't think there's any way to buy 1:1 so to say. it's either buying things like gift cards and selling them on "paxful.com", but with a huge % loss. or you could try this:

I never did myself, seemed problematic.

unless you can buy via like ebay perhaps if there's authorized sellers? but, surely the smartest way to go about it would be simply withdrawing. or maybe sending it to a friend who could buy for you or something.

That's hardly a very efficient way if you want to make money? logically you select a good bounty, which obviously is tied to an ICO.
why can't you invest in the ICO if you believe the bounty tokens will be worth anything? 

the circulating supply can't be used as some marker of performance? do you mean a low circulating supply vs the total supply? if so, isn't that more cause for concern?
do you mean the actual amount is low? then it only matters when compared with the price.

and as previous poster said, I fully agree. there is very little possibility that any coin or token or anything, will ever become "the" currency.
bitcoin could theoretically implement most things that other coins has.

however, what other coins can never achieve(unless they fork bitcoin), is the actual distribution. if "someone" creates a new currency today, obviously the distribution is very skewed. or, if it's mining, the difficulty is low early on. the problem today is that people always find these and "jumps on them" right away, buying in cheap/mining with low difficulty, and obviously, some people will have a great amount of these IF the difficulty/price ever increases(as in, being more popular). bitcoin is unique in that regard because for years people traded it at very low prices, mined with low difficulty, and over time, it has been distributed in a way that no other coin ever can achieve.

I wrote a thread about investing in icos here, but part of what I wrote is that one has to be very careful when selecting an ICO. a lot of ICOs are stupid to invest in, partly because of how they allow "private investors" to purchase at x% discount than everyone else. so if the ICO ends at $1, maybe 10% of the supply was bought at $0.1, and they can happily dump it for $0.5!

many people fall for the false promises of ICOs, and well, stupid people will part with their money sooner or later.
but as you said, it's not always the case - so, if people believe they've found a good ICO, then they buy.
the issue is just that many peopel don't know what's a good ICO!

I'm wondering if anyone know of any sites like etherscan, which actually looks up the token-prices on decentralized exchanges? I believe etherdelta only shows prices from coinmarketcap.
it'd be good if there was an easier way!

isn't for example the american government making it more difficult to participate in ICOs for americans? and in the rest of the world aswell, demanding KYC for example, but americans must be "US accredited" in some cases(atleast if the ICO is going to do well in america)

Ripple is already very high up, so it depends what you mean by game changer? as in a massive price increase, it can't go too far without multiplying the current market cap, so I don't think one could expect too much in the near future! but later on the market cap will of course grow in general.

instead of looking to various months and events, you could look at this for example: https://www.turtlebc.com/tools/buy_percentage?period=3years
to see the market trend, buying in at the right time in the trend is better than buying based on things that people believe happens at specific times!

Ripple seemingly has gone up quite a bit the past days, after the earlier drop? anyone know what caused that? I haven't seen anything new?

if you're looking for decentralized exchanges, I googled and just found this list: https://github.com/distribuyed/index

well what's your goal with the site? to make money? referring people to different exchanges? ads? there's sooooo many sites out there already that are just the same thing as any other, if you can't offer something unique and if you are in it for money, there are surely better things to do!

did you try searching on their relevant blockchain explorers? here's one for NEO: https://neotracker.io/
