Its a good idea though. But it would have been better if you divide the total funds in a ratio of say 8:2 so that you can save about 80% in stable coins while keeping de remaining 20% in a volatile coin, probably BTC so that your funds can appreciate small by the time you are withdrawing your funds

I would advice you to put it into bitcoin because of its foreseeable longterm profit but sincerely speaking the investment window of 6months which you gave is quite short. 6-8 months ago and bitcoin was trading under $4k. The market is too volatile to say the price of btc in the next 6months. You might have to wait a bit longer for gains

Stable coins don't bring anything. And I am not sure what's more trustworthy - banks or some more or less known institutions that issued stable coins.
An idea was to invest for growing the value. Investment means risk. And investments need time and 6 months may not do, especially in crypto, which is prone to big fluctuations.
But if he does so, then I would advise more than Bitcoin only, some amounts can go into something else. Maybe some small amounts into altcoins, maybe some amounts into gold or stocks... diversifying uses to increase the chances for a good outcome.

However, OP should keep in mind that exchanging his money into something else and back means fees to be paid.

So there's no good solution imho.
9902  Bitcoin / Bitcoin Discussion / Re: Would you close your Bank account, when your Bank turn against Crypto? on: November 18, 2019, 03:11:49 PM
Where I have my account I also have a pending loan and also it's the bank preferred by my employer.
So unless I change my job and I also get enough money to pay back my debts, the chances to leave that bank are slim.

And I hope that by the day my loan is paid, Bitcoin also gets recognised properly as a coin everywhere.

I'm sure he needs help.

9904  Bitcoin / Bitcoin Discussion / Re: Google possesses threat to bitcoin. What do you say? on: November 17, 2019, 08:48:49 PM
Quantum supremacy was a lie or a failure attempt. may be they failed to break cryptography but they showed potential risks and whole crypto industry suffered

Quantum computers are not as stable as the "commercials" show them. They are not really usable yet afaik. And if the manage to crack Bitcoin, (way too) many other things become unsafe. And however, Bitcoin has certain protection and I expect it be quite low in the list of quantum tasks. I expect, for example, a good weather forecast be much more higher in the list.

Crypto provides security, can secure privacy

Bitcoin is pseudo anonymous, one has to be very careful if he cares about his privacy. (On the other hand there are plenty of coins that do offer privacy by default.)

What if google attracts millions of new investors?

Bitcoin is not just another thing to invest into. I expect more and more will understand that and choose Bitcoin.
Google, on the other hand, is just one successful company. People invest in companies before Bitcoin existence and will continue to do so. It doesn't really affect Bitcoin.


All in all, none of these "problems" are actual problems. Calm down  Wink
9905  Economy / Trading Discussion / Re: Are you holding Bitcoin? on: November 17, 2019, 08:21:59 PM
And for investors who like to "trade", certainly Hold is not their choice, because the short-term waves are the time when they make the best profit.

I think that even traders may be holding some coins. I see it not a contradiction, instead a "diversification" of the ways to gain some more and maybe lowering the risks too.
I did a bit of trading in the past, I do hold a little too, but I had to spend too.. more than I wanted to. So I can't say I am a true HODLer...

Wasn't Binance allow you buy Bitcoin with credit card? They will not ask for papers under a certain amount (2 BTC/day withdrawals), but they will ask for some personal information anyway.
If that's OK for you, research in that direction.

I actually don’t see scandals in any form ever stopping. Especially not the internet kind. As technology progresses, so does scandals. Securing crypto isn’t just about technological security but also about humans’ awareness.
For example, it is not advisable to keep cryptos in exchanges because it increases the chance of your crypto been stolen.
It also not advisable to keep cryptos in devices you are not assured of very high security. It is best cryptos are kept offline (cold wallet) than online.

You are right. Just too many people are not aware of all this. They don't read (enough). They don't understand that if the coins are gone, they're gone and nobody will reimburse them.
And most start shouting (instead of reading) when they get into troubles because they didn't read.

one of most dangerous disadvantage of web wallet

My first ever purchase with Bitcoin was a total mess. Why? Because I've been using back then a custodian web "wallet".
The platform was expecting the payment get sent within a number of minutes, the wallet was optimizing the fees and sent (much) later and I've spent unnecessary amount of time to recover my money.
It ended well, it was not a high amount either since I was testing, but all the other payments I've done from proper wallet and all went out good.

There are more and more examples pointing to the direction that web wallets don't worth be used. We all learn and do the step forward sooner or later. The sooner the better though.
9909  Bitcoin / Development & Technical Discussion / Re: How can you detect a risky transaction before a single confirmation? on: November 17, 2019, 04:03:24 PM
If you broadcast a tx 9.5 mins after the last block, it might cost 10 sat/byte to get your tx confirmed in the next block but if no blocks are found in the next hour and a half, it might cost 70 sat/byte to get your tx confirmed in the next block and this amount may stay elevated for some time.

In the scenario I am describing, an attacker could make a deposit 1 second after the last block was found, if a block is found within 10 minutes, they could just withdraw their deposit, but if no blocks are found for say an hour, they could make a high probability bet and attempt to withdraw if it is a loosing bet. In this scenario the market cost to get a tx confirmed will have increased due to a lower supply of block space (even if this is temporary). 

I didn't say that your scenario is impossible. I only said that it's not 100% risk free. There can be some blocks found very quick, there can be low fee transactions included in them (CPFP for example), ... which can spoil the plans of the attacker. However, his chances are still very high indeed.
We are on the same page: private (proper) wallets are not to be trusted for 0-confirmation funding.
9910  Economy / Web Wallets / Re: [blockchain.com] Is it really secure ? on: November 17, 2019, 03:54:35 PM
there could be a web_wallet which has a full control by the user

As long as MEW is opened as a web page, I don't know why it would be so different from blockchain.com; if at the point something is downloaded and run locally, an exe is also fine by me.
So I am not sure why would people use web based wallets at all. If one doesn't want to install, there's always Electrum-portable at hand.

But as long as people don't mind using even custodian services - from exchanges' wallets to Xapo, Bitpay and so on - meaning wallets that are not in the list of recommended wallets at bitcoin.org, I think that we may be overthinking something.

The main factor who caused this large adoption , IMO , is its brand name <blockchain> and how it is still missleading newbies. For experienced users, i doubt if they still using it or any other web_wallet.

Newbies should start with bitcoin.org. That's what we should recommend.
Newbies can be misled by "blockchain.com", by "bitcoin.com" and maybe others too. They have to learn to read the information around them. Sadly in all search results the paid ads go in front, although at least nowadays Google shows bitcoin.org for searches for bitcoin or bitcoin wallet. It's a start.

It's written in far too many places that web wallets are to be avoided, no matter if they contain or not keywords like blockchain or bitcoin. One has only to look around instead of going head first.
9911  Economy / Web Wallets / Re: [blockchain.com] Is it really secure ? on: November 15, 2019, 01:26:31 PM
In theory you can install Telerik Fiddler and see what data it "sends home". But since probably some already did that and didn't complain, it should be fine.
Of course, since it's a website, they can change it whenever they want and "come with surprises".

However, if you have such concerns, why do you use web wallets at all? Buy/start using a hardware wallet, install a proper wallet onto your laptop or smartphone and you are set.

Momentan am 15 sMerits, cu care voi ajuta 15 newbies, insa daca voi mai primi, as putea suplimenta campania. Voi acorda doar 1 merit per cont.

Foarte buna initiativa. O sa ma uit si eu peste postari cand apar si este posibil sa acord si eu merit pe ici-colo.
As adauga la punctul 7, asa, de siguranta, ca se exclud si traducerile automate.

You mean that company that when you put in your recovery words, it sent it over the internet to a govt url to spell check it?

 Grin You can also put it like that, yes. Officially they simply didn't protect them, allowing the spell checker send them to whoever wanted to "help" with them  Grin

9915  Alternate cryptocurrencies / Altcoin Discussion / Re: Central Bank Cryptocurrencies Are Pointless, Says Ex-Federal Reserve Chairman on: November 14, 2019, 11:01:09 AM
Do you agree with Alan Greenspan’s statements about central bank cryptocurrencies are being pointless?

Let aside crypto promotion, which central banks don't want to do, central bank cryptocurrencies are not pointless.
They would offer an alternative - a more trusted one if implemented correctly - to all the known stable coins, existing (USDT, GUSD, ..)  or not (LIBRA).
9916  Alternate cryptocurrencies / Altcoin Discussion / Re: Alt-coins with practical use on: November 14, 2019, 10:53:30 AM
I also vote for Dogecoin, Litecoin and Waves.
Although correctly said, there are other better suited coins for fast and low fee / 0-fee transactions, some still use Dogecoin just because almost all exchanges list it.
Litecoin (and sometimes Dogecoin) may still be used by some exchanges as the basis for exchange (instead of Bitcoin) for very small value coins, having LTC-WhateverCoin and no BTC-WhateverCoin.
Waves is a very easy and cheap platform for tokens and has a working DEX (and other features too). Although it's drowning under the huge number of useless tokens, it has its utility imho.


OP, maybe at some point you'll adapt the initial post and enhance the list?
9917  Other / Beginners & Help / Re: Custodial vs Non Custodial vs Browser Based Wallet on: November 14, 2019, 10:38:41 AM
For example, it is much safer to use a web wallet than to carry cash in your wallet in Brazil. I am carrying about $30 bucks in my wallet. I understand the risks, but it is worth. I won't become a poor guy if I lose $30, but it is very convenient to have some cash at hand. The same goes with a web wallet.

Exactly. Under certain amount of money, web wallets are "okay". If they "steal" your money, in a way or another, it's no biggie.
And under certain amounts people are also careless with their wallets, no matter how good the software is. And under certain amounts it's not worth it to buy hardware wallet.
The fake "Electrum 4.0" has proven all this much better than we'd like to admit.
9918  Bitcoin / Press / Re: [2019-11-12] Bitcoin Mining IPO Could be the New Gold Rush on: November 14, 2019, 10:15:23 AM
Although selling crypto miners is (expected to be) a good business, I'm not sure what they would do with the IPO money.. expand their production in US to avoid tariffs?! But then the production will also get (much) more expensive.
So I am not sure who will be the ones who would benefit more - the investors or the companies? I guess that's the companies.
So it's not really a gold rush.

9920  Bitcoin / Development & Technical Discussion / Re: How can you detect a risky transaction before a single confirmation? on: November 14, 2019, 08:58:46 AM
a non-rbf tx can still be "replaced" (double spent) without the assistance of a miner. If there are many unconfirmed txs competing with each other (such as what happened in late 2017), an unconfirmed tx may eventually get 'dropped' by most nodes, including the nodes the miners use, which would make it trivial to double spend one of the inputs as long as you use a sufficiently high tx fee.

Yup. That's why I suggested OP to allow 0-conf to certain (custodian) wallets which don't allow users do rbf at all.

An attacker may for example, broadcast a tx immediately after a block is found, and if it has been at least xx minutes since the tx was broadcast, make the risk free bet

The previous number of minutes between blocks doesn't necessarily give a hint for the number of minutes until the next block, so it's not risk free. It may reduce the risk (debatable), but doesn't make it risk free.
