there is nothing to solve!
there are always going to be idiots who hear something and make conclusions based on that just because they don't understand what things such as "premine" and "ninja mine" mean that doesn't mean bitcoin needs fixing, THOSE people need fixing and that is out of our control.

Litecoin is a poor copy of bitcoin and copy coins will never be able to perform 10% as bitcoin let alone replace it. as for ethereum, it has too many problems to even become a big project. problems such as centralization and lack of immutability are the most serious issues. other smaller ones is its lack of scalability and unlimited supply. not to mention that it is a token not a currency like bitcoin.

regex is not enough since it can only check validity of characters. i don't know how JavaScript works but basically you need to add a function instead of that one liner to decode the strings using Base58 encode/decode technique which would mean converting it to its numerical value then hashing the byte array using SHA256 twice and taking 4 bytes of it as checksum then see if it is correct. then pass it to get the balance. more info: https://en.bitcoin.it/wiki/Base58Check_encoding

i didn't mention Bech32 since the btc-priceimg and the blockchain.info API it uses don't support them but here is the link to its documentation: https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki

as i explained in the duplicate topic that got deleted, since this is not a common thing that wallets allow you to do when they create a wallet you will never normally end up with wallets in these paths so there is no wallet or tool that supports what you want.

your only option is to do what HCP said with a script, or if the number of private keys isn't that high (like having less than 10 keys with balance in them) then use a tool like Ian Coleman's BIP39 and get individual private keys, then create a brand new wallet and sweep all of them there and don't repeat the same mistake of creating many wallets with paths like this.
run that tool offline by downloading it from source here: https://github.com/iancoleman/bip39

Protonmail is 10 times better than Gmail, not to mention that we are comparing a company located in Geneva, Switzerland with a company in US! by default Google will betray your privacy

but in the end if you want true privacy then you shouldn't rely on any of them. simply encrypt whatever sensitive information you have OUTSIDE of the email provider webpage with whatever strong encryption technique you know of and then only use their service to transfer the encrypted data.

i am finally out of merits to give...

if someone creates a bank account in their own bank and then give you the account number asking you to deposit money in that account while telling you it is "your account" will you believe them and send money to that account?
that's the same with bitcoin! when they created the wallet, they were controlling the keys to that wallet not you. and when you sent money to that wallet, you donated your money to them.

it is not 7 months, it has been years. and it is not just Electrum, this is a well known way of spreading malware by disguising it as a well known application that people use. and this method only affects people when they are lazy about verifying what they download which includes creating a web of trust and finding the right PGP public key to include in it and verifying the downloaded binaries. but since these steps aren't easy specially for the windows users, they tend to skip it altogether and end up infecting themselves like this.

no matter how many times this is being repeated, it won't come true.
people aren't buying bitcoin just because Facebook may or may not create a shitcoin a year from now. people are buying bitcoin for the same reason why they have been buying it for the past 10 years that price went from 0 to 0.01 to $20000!

but we are already relying on the "parallel system" that is called fiat and banking system. them "upgrading" their system to use blockchain technology doesn't change anything.

bitcoin will not "connect" to anything ever, specially when that thing is 100% centralized. the only thing that can happen is if that centralized service (in this case Paypal) started adopting bitcoin themselves and accepted it in their platform.
in this case Paypal will some day start letting people convert their paypal dollars to bitcoin and vice versa because they will have no other choice if they want to stay in the game. but it will happen many years from now when we are closer to mass adoption.

another big waste of time trying to get some attention and video views up by hyping about Satoshi Nakamoto's identity and fooling themselves while wasting other people's time who actually go ahead and watch the thing
in the end everyone will realize that Satoshi (the real SN) hid his identity intentionally and he is not going to change his mind at all for no reason. so he will remain anonymous.

the ICO thing itself is nearly gone but the thing it represented is not. ICO boom was not a new thing, it was new form of something that repeats every couple of years. and that is creation of a large number of new projects that people bet on for hopes of big profit. ICO which was basically smart contract creation made things easier for copycats to create a new project with least amount of effort unlike before where they had to run a whole stand alone blockchain network to run a new shitcoin!

i can see the same trend repeated again, probably in 2020 or at least end of 2019. the copycats have not gone anywhere and market is still filled with gamblers who only follow the hype. we are in for another rearrangement of so called "top" altcoins pretty soon.

you might want to add some more encoding checks (base58 and bech32 if you could add it) to the values you capture as "addresses" instead of a simple regex check for characters. right now it seems like it is possible to catch something like a transaction ID that starts with 1 or 3 (32 byte and having 0-9 and a-f) as an address.

the best thing you would be doing is avoiding address reuse. and this can protect you against some bugs in some of these HD wallets without you even knowing it. for example the case of blockchain.info reusing k values.
when creating a EC signature you select a random value called k, if you reuse this k your private key can be recovered easily. in this case when you have more than one input in one address and want to spend them you are signing once per input. if your wallet is broken and is giving you the same k, you reveal your private key instantly. but if you have more than one key and only use them once, even if you are reusing the same k it is impossible to recover private key since each key is only used once. https://crypto.stackexchange.com/a/46622/67204

if you want to waste electricity and lower the lifespan of your computer hardware by putting a lot of continued pressure on them then  at least start mining altcoins! that way you can at least earn something for real instead of wasting your time on something that obviously not going to work not just in a couple of days or years or decades,... it won't work for a million years!

please stop trying so hard to associate bitcoin with libra, they have never been any connection between the two and there never will be. bitcoin has risen millions of percentage in the past 10 years without libra or any other shitty project like that and it will continue to rise without them too.

wrong.
the USD value of it seems to be higher because bitcoin price is higher. in other words bitcoin went up 330% this year and that rise pulled the USD value of all altcoins up, 150% shows it has actually dropped significantly!
and if you look at the ETH/BTC chart you can see that it was worth 0.041BTC and now it is worth 0.025BTC which is nearly 50% drop.

it doesn't matter where you download Electrum binaries from, if things were more serious we could simply create a torrent file and start sharing different versions through the torrent P2P network so that anybody could download it.

but only as long as they verify the signature of the files they download correctly and with the correct PGP public key. https://github.com/spesmilo/electrum/blob/master/pubkeys/ThomasV.asc

they have been active all this time, you may have missed them in the news each day coming up with new weird things about bitcoin and regulating it!


the difference is that Facebook and their coin are not "crypto", it is a centralized money printing machine that decided they wanted to start printing their own money.
the difference with regulation regarding this is that now that it is centralized the government has a door to kick down so they can easily put pressure on them and force them to do anything they want. unlike bitcoin that there is no company or centralized place to go to and force it in their desired direction!

well, some people don't see the potential that bitcoin has and it has always been like this ever since bitcoin was listed on exchanges for trading and price was somewhere around $0.01. they have been selling their coins as soon as they got some profit like 3x like selling at $0.03 and got out completely.
usually these people come back though, later and usually in the peak of the bubble and lose money next time because of FOMOing.

whether the Electrum website is down or not has nothing to do with your "cold storage" and whether you actually lost any coins from it. if you did really lose anything it is because you leaked your secret information such as your seed words in some way to a hacker that stole your coins. try to think back and see how you leaked them.

because it is NOT dominance. it is only market cap.

what is market cap? it is multiplication of supply and price.
before 2017 the shitty website that started this "dominance" nonsense only contained about 600-700 altcoins and the sum of all circulating supply was around 1,800,000 million. so "dominance" at this point is calculated with 15 million bitcoin supply divided by 1,800,000 million altcoin supply and it is 90%.

then the 2017 craze began and the ICO shitshow intensified to the point where each day we saw a new shitcoin pop up with billions of supply. by the end of 2017 we had somewhere around 3000 altcoins (400% increase) and the total circulating supply grew to 30,000,000 million (1566% increase).
so "dominance" at this point is calculated using 16 million bitcoin supply divided by 30,000,000 million altcoin supply and it is 30-40%

then in 2018 those shitcoins that were created started dying and every altcoin pump started getting dumped. with each losing at least 90% of their value. today we are only seeing 2250 altcoins from that near 3000 (25% Decrease) and the total circulating supply has shrank down to 12,000,000 million (60% Decrease) as a lot of them died or were delisted.
so "dominance" today is calculated using 17 million bitcoin supply divided by 12,000,000 million altcoin supply and it is 60%

that is why it is not "dominance" it is just a ratio of supplies. not to mention that what coinmarketcap.com is calling "circulating supply" is not really "circulating" it is total supply. if we remove the premines and coins that are not in circulation most altcoins lose about 70% of their market cap specially big coins like ethereum and ripple.
