The best option would be to use Trezor now and they support it. Never trust exchanges or online wallets for your funds.
Alternatively, you have Omniwallet which I believe is open source and reputable.
If you're planning to hold them for long term basically, then you should know that Tether is based on Bitcoin's blockchain which means you can store them in any bitcoin address, just make sure you have control over the private keys. Whenever you want to spend them, you could export the private keys and use them in Omniwallet for example.

I'm currently working on an open-source and privacy-based portfolio app, it's a vanilla Javascript SPA that gets all market data from public API's, while the user's portfolio data is stored on client side and never leaves it. If you want, you can pm me so we can discuss joining forces, or I can just share my experience.
I would definitely be interested in doing that, thank you! I'm currently making a file in Notion.so with the list of features and prioritizing everything. I will send you something to look at in the near future, once it's done. Not only portfolio, but maybe it could also create a ranking/rating feature for each person and give them an overall score based on their good/bad investments.
And another feature I'd like would be something similar to Suubee where users could perhaps monetize their trade moves and create signals that people would directly subscribe to. And PLEASE use tradingview / avatrade charts
Lastly, as you said, NO INFORMATION SHOULD BE STORED by the app on its servers, everything should be user-end oriented.
I've never used Suubee before but I will take a look and see what exactly you're referring to. Have the option to follow others portfolios. Even if they are fake portfolio. I think it would be interesting to be able to follow the action that some people do in the trade. Maybe even pay to follow someone who gave tips and explain why he took certain actions.
Show some options that you have taken as a trader. For example, what is your stop loss, your leverage in Bitmex, your liquidation price etc. I think the most important in a portfolio app is that you can have all the necessary information about your investment anywhere. It is risky, for example, to access your account at an exchange when you are on the street, on a bus.
Unlike the other services out there, this application is meant to be open source and privacy-friendly, I'm not planning to store any info about users on external servers and without that, your suggestion cannot be done. technically it is possible to do it without making it centralized or have a server that stores user's data. it can be done perfectly fine in a decentralized way. i don't know what the point of it would be because i never use a "portfolio app" and think it is a bad idea to even have a portfolio in altcoins but i say it is possible. each app can have a functionality similar to a peer on a p2p network. people can have the option to share their settings with others by giving them their "node" address. it would simply be a socket that listens on an open port and communicates with anybody who "contacts it". you can write a simple messaging protocol (similar to bitcoin's for example) and on request it sends out the portfolio of the user to the asking node. then any update can also be pushed to the connected nodes. obviously there is little privacy in this design but someone who is willing to share his portfolio is already giving up his privacy! You definitely have a point, I haven't thought about it this way, to be honest but like I said this may come in the future but definitely not in the initial release.

In addition to what has been said above, your privacy policy, terms of services are not made. Your social media pages are empty, the team behind this project is not known.
There is a lack of validation rules and error messages when it comes to making an account, login etc.
In other words, you didn't put much effort and people are not going to trust you with their funds for that reason. The way it's looking is that you're trying to attract people with this daily bonus feature so you could get people to deposit their money.

In fact, you don't even need a credit card for most items on Amazon.de, OP. You can even buy an Amazon.de vouchers for the stuff you want and use it at checkout. Bitpanda lets you sell Bitcoin for Amazon.de vouchers (needs verification though I think) but there are others too like localbitcoins euro traders. The crypto to voucher works best if you don't have a credit card.
Note: 2018 info I haven't checked if this is current.
I wasn't willing to do any kind of verification so I looked more and found that Bitrefill.com sell Amazon.de gift cards. I appreciate the help.

Why are the silvers accounts more pricey than the Gold nova and MG ones as well? I also can't seem to find the bitcoin option? I added accounts to the cart and I can only see PayPal and credit cards.

There is a reason on why escrows don't do these transactions. Gift cards can be chargebacked just like PayPal transcations for example so even If redeeming the card works, issues could happen afterwards and escrows usually don't want to take such responsability.

I'm buying Amazon.de (German) gift cards at 80-85%. I'm buying around 100-150€.
Gift cards can be chargebacked so If you're not a reputable seller, I'm not interested in trading with you.

Alternatively, you could use Blocknomics or Chain.so API. It all depend on what you're trying to achieve but since these APIs meet your needs, I suggest checking the rate limits.

As the title says, I have 70$ and looking for 1:1 exchange for PayPal with preev.com rates. I don't mind going first with trustworthy members.
I'm not willing to trade with anyone with negative trust or low ranked so please don't bother here.

User 'BitInka_User' has not chosen to allow messages from newbies. You should post in their relevant thread to remind them to enable this setting. How I can provide you my email in your platform? 3 weeks no solution, I had only 1 answer from support that they are reviewing my operations. Since then no any response, no information about my account and withdrawal for 3 weeks!
I gave you merit, you're a junior member now. BitInka_User was last online three days ago so you might have better response If you try and private message him again.

If you provide scammer profile links and links to their posts here. It makes it easier to check out on them and get them tagged. So if you can. please update the OP with links.
I doubt the posts still exists because I searched on the forums and it only gave the OP's thread a result.

Shouldn't be there some kind of verification (proof of ownership) for the email address? I managed to make multiple wallets using the same email address and different passwords, is that the expected behavior? Nevermind, that should be it since nothing leaves the browser and goes to your servers. Aside from that, few suggestions:
- I'm not sure about sending, but it might be a good idea to support native SegWit (bc1). - If you're going to enforce people to use a strong password, maybe just give them a hint of the characters and length they should use. - Instead of a blank page, It's better to display an error message in case the webcam is not plugged or cannot be accessed.

The buyer nationality doesn't need to be Danish. Anyone could buy your item on Amazon and receive it, then ship it to you to the address you want. Or your order and pay the item and give the address of the person. Obviously, it would need to be someone in the US. Of the person doesn't want to give his personal address he can pick the box at a "Pick Up Point"
I found another solution and apparently everyone is using Amazon.de and Amazon.co.uk which ships to Denmark. But just to be sure I got you right. If I find someone who could buy the item from a danish website, all he has to have is a credit card? He doesn't have to be a Danish citizen or anything and he could just fill the shipping info with my details?

If you want something that has both BTC and ETH, then you have Coinomi which is probably the most used one, Eidoo, and Enjin. Unlike the options suggested aboveo, these wallets are not open source though, and even though there have been no reports about a scam, use them at your own risk.

You can start by checking this list. The 'can be anon' column should represent whether you'll need to provide personal data or not or also check the virtual ones because you want to simply do online shopping (not that many). As for the countries, cards should work everywhere Visa or MasterCard are accepted, It's only ordering the cards that is limited to certain countries, not using them but as said above, it could be very hard to find something with all your preferences.

1. Why fees on deposits instead of withdrawals? 2. You're based on Czech Republic and yet the website is available in English and French? (After selecting French, nothing happens). 3. Your blog posts are copied from other sites like newsbtc without mentioning the source. 4. Where are your offices? 5. Who is the team behind your exchange? 6. Your three last facebook publications have 12 likes, that looks like bots more than a coincidence.

Do you think it will be ok to contact people on forums and other marketplace to start selling on our marketplace ?
It depends how you're going to do it but I don't suggest doing that, it might be considered as spam and you'll have negative trust in your profile which will have a bad impact in your service.

I'm not sure these exchange features are something we need to be honest. There might be some problems in the future where people are forced to do KYC verification and even though Trezor will probably be using a third party service like Simplex in this case, people would still blame Trezor so as convenient it is to use ShapeShift, Changelly, Paybis etc. directly from your wallet I wouldn't suggest it that much.

If this version belongs to OutCast3k why then they do not delete or update this version? I looked at /JS/ there is not even a standard RFC 6979 ( https://tools.ietf.org/html/rfc6979) My conclusion came based on two things: 1. The current repository has version 1.1 as the first release which means that 1.0 might have been somewhere else (in the link you gave). 2. Whoever posted that release wanted to give credit to OutCast3k. I don't this is likely because coinb.in was not famous back then, so someone hosting something for phishing people is unlikely. Either way though, I wouldn't suggest using it even If it was from the original creator, because it might contain a lot of bugs.
