I have my own experience where I should stay at night to see if the price getting dumped or pumped by the chinese guys.
Because a coin is used worldwide and people live in many different time zone I should check when to buy and when to sell.

I have 1x OkayFreedom VPN Premium 1 Year license and want to sell it for bitcoin.

Price is cheap 0.01btc

I have only one left.

I haven't invested in any ICO but it contains the risk, because the price after the ico can drop and you can lose.
But also it is a good opportunity to make a profit, I saw many coins that their exchange rate was way to high than the ICO price.

We have take a good lesson from bter and other exchanges that were hacked recently.
But the bter hack was in February 2014 and it has been a while since they don't give back our money, i have a good amount there unfortunately.

But you didn't reliazed that you can give a vouch copy to a trusted member or to a higher rank.
And send a vouch which after that you receive a review about your product or service which most of the time increases the number of sales.

Unfortunately they don't give back to us our money.
I haven't heard from them for many months, their support don't reply or reply after few months which is a long delay.

Please check my PM
Want to confirm that I have received the payment and don't worry we are human and sometimes we are very busy in the life outside.

Here is a video which explains maybe better What is RDP? and How to connect it ? https://www.youtube.com/watch?v=UsAuHzXCzoc
I think that the guy selling those RDPs should fits your needs.

You should receive rdp details as follow: ip/username/password the same as a VPS will oferr you to access that windows, I don't know if someone else record your data but the RDP should work enough for you (RDP is Remote desktop which you connect through remote desktop connection)

Not sure if a windows RDP should work for you but check this guy selling it:

When you get retired sometimes means that you are not able to work anymore so bitcoin is just money that is for the work we do, so just a kind of money.
Thinking from now about the retirement is a bit early but at least thousands of bitcoin at current value should be enough but who know what price will have bitcoin after 20 years.

The OP was online a hour ago and I expected a reply from him but maybe he didn't see our comments.
Buying through internet is a big deal because you can't check in detail the car features, scratches, stability and other physical things, anyway selling for bitcoin is good and if this car worth more than 11k€ then it worth buying especially with bitcoin.

Most of the altcoins start with a crowdfunding and with investing (ICO) at most of these funds are accumulated in bitcoin.
By this not only that these altcoins become popular but also bitcoin become more popular because through bitcoin they are investing in another cryptocurrency.

I have invested and trader many different altcoins and saying the truth i couln't sleep well because of the stress.
And the trading consumes lots of time if we don't use any bot like c.a.t but I think saving bitcoin is better as bitcoin stays there where it is, like the clean gold.

Ask this guy as this provides lots of virtual credit cards and maybe he have any of the special prefixes for visa cards.
I have seen also on other forum so he should be trusted but always trade through escrow: https://bitcointalk.org/index.php?topic=1190159.0

I congratz for the initiative to create this tool but I tried to open from many different browsers and I always get a blank page, on chrome I think it freezes a bit my screen but still no result even after half a minute.

I haven't seen anywhere where you can pick the first digits of the virtual card, you may ask the websites that offers virtual (bitcoin) debit card and ask them if they can ask the issuer about these prefixes.
Btw, why are these prefixes so special for you? Aren't all visa cards the same?

This question is very tricky because we don't know or don't have the knowledge to predict after 20 years what will happen with the internet neither with the bitcoin.
I think that you should count a million dollar equivalent in bitcoin, so around 2,000BTC or more I think should be enough.
