Stop living in the past!

I dont know who needs to hear this but, stop living in the past!

Ever heard the saying coulda' shoulda' woulda'? Well it will eat you alive if you let it.

It doesnt matter that you missed out on buying bitcoin at $100, $1000, or $10,000. All that matters is that you know about it now and from this day forth you are able to partake in one of the most empowering technologies ever invented. From this day forth you can secure your wealth from inflation, seizure, and censorship.

So stop worrying about missed opportunities and look forward, keep stacking, and appreciate that you have that opportunity.

If you got emotional about the dip today, you need to manage risk better

Dips and rallies is part of investing, it happens in every asset class except t-bills. If you got stressed out, you probably need to diversify your portfolio to appropriate allocations for your risk tolerance. A 100% cryptocurrency position is bad strategy, or no strategy at all.

Two out of the top three paper wallet generation sites are dodgy (bitcoinpaperwallet.com & walletgenerator.net)

So... I had look at bitcoinpaperwallet.com and walletgenerator.net sites' javascript code and did some interesting findings. They are concerning to say the least. Both of the sites use the exact same javascript code and are thus likely operated by the same person/persons.

When paper wallets are generated on these sites (online or offline), their public addresses are not created using the seed or private key provided by the user. Instead there is a list of 60 pregenerated (base64 encoded) public addresses embedded in the javascript code which is loaded with the site. The list's contents change with every reload of the page so the public addresses are apparently generated by the server before the page is sent over. If the user saves the page and goes offline, the list of public addresses is also saved and used offline as well.

What does this mean? I believe there is a high risk that any paper wallet created using these sites have public addresses printed on them which belong to wallets controlled by whoever controls the servers of these sites. There is a generated private key on the paper wallet as well, but it simply does not match with the public address. Anyone sending bitcoin to the public address will be sending money to someone else only to find that his/her wallet is empty (and always was) once trying to use the wallet.

I would appreciate if someone else technically minded would check whether I'm right about this. Save the html and the search for 'eckey_test' (you might wan't to prettify the javascript code though, https://beautifier.io/). This is the list of suspicious pregenerated public keys.

Edit: A correction to my analysis. Actually there seems to be 60 public-private key pairs embedded in the code (see 'eckey_test'). If you simply go to the site and generate a wallet you are served one of these pairs (after Base64 decoding). But they are still seemingly pregenerated server side which is dangerous (the whole moving your mouse thing does nothing to change the list). The above-mentioned case where you end up with an invalid pair happens when you try to provide your own private key. You'll end up with a wallet with correct private key and invalid (and dangerous) public key.
