I have some savings -about 50k usd- and so far I've been thinking about mutual funds and Forex and Bitcoin
Any advice/recommendations/ideas? Does anyone here do investments?

All I see is down and down, we couldn't even break into 6s during the last rally.
If bitcoin isn't valuable then why use it instead of a new coin that doesn't have a few powerful people that all ready control all of it?

Bitcoin , is a strange word for me a month ago, and I have never heard of it before. But now, Bitcoin has consumed a lot of my work time, and even found its way to my life time. Everyday I find myself checking my computer or phone for the latest news of Bitcoin, which has opened my eyes. And I'm interested in it gradually.Here, I just share my ideas with you. I believe that Bitcoin has a promising future. There are some reasons to support my ideas.
On the one hand, from the adoption prospective, you can find Bitcoin in business, education, entertainment and other industries. In business, a major New York law firm decided to accept bitcoin. The firm says they recognize that bitcoin is here to stay, and are already playing an important role in business and the economy. In education, the Immersive Education Initiative(a not-for-profit organization) on Monday launched what is said to be the world's first global education scholarship fundable through bitcoin, which is good for spreading bitcoin. In entertainment, Snoop Dogg expressed interest in accepting bitcoin for his latest album, and former Spice Girl Mel B actually went through with it by offering her single up in exchange for the digital currency, which is an interesting development in the Bitcoin space and highlights the community's companies and other notable entities. On the other hand, Bitcoin seems to be have a healthy environment. The Financial Conduct Authority--a regulator in the United Kingdom--has made it clear they want to help the development of bitcoin business by having a regulatory environment that supports them, which can promote and create room for Bitcoin into the market. A permissive regulatory environment is key to helping digital currencies flourish, especially when speaking of bitcoin. Thankfully, it's nice that not only Uk regulators, but some other regulators, have recognized that point.
 From the above, Bitcoin will be valuable, because it can be used in real world, not only online world. Therefore, I believe Bitcoin will help the world.

when we already have crypto currencies, master cards, paypal and other shit, why do we use cash?

Which Bitcoin Client do you use and why ? If you use web wallets, please do mention which one is your choice and why ?

The tx is large (17K) but it includes >0.1mBTC per KB in fees, it has no double spent or unconfirmed inputs, and it has no dust outputs.  The interesting thing is that the tx was sent from Bitcoin Core (v0.91).  That node does not have direct connectivity to blockchain.info so it must have been relayed by at least one peer.  The recipient node is also using Bitcoin Core v0.91 but the tx is not in the memory pool and my assumption is that the recipients peers are dropping it.  The question is why?  Possibly a difference in relaying rules on older nodes (and the recipient is unlucky enough to have all older nodes as peers?  As of the time of the post it hasn't been included in a block but I am more concerned with what would keep it from being seen as an unconfirmed tx by the recipient node.

On edit: ok it was just included in a block and the recipient node instantly recognized and reported the confirmed tx but why wasn't it relayed prior to being confirmed.

Almost certainly.


Probably


Not easily.

You might try looking into Peter Todd's replace-by-fee-tools, specifically bump-fee.py for an alternative.


Then send a second payment (with a fee), and request a refund for the first payment.

If you want to make sure that Bitcoin Core always includes a fee, change the default fee in "Preferences" to 0.0001 BTC.

Read an old post similar to this, though the price was something like 100. 

I have tried faucets but they are useless and slow.

hey gang,

I was wondering which cell phone is the best phone to use for moving bitcoin?  

I recently purchased some coin, took a picture of the receipt and tried to attach to email but couldn't. pretty sure it's the iphone because I couldn't upload the picture via iphone email client or when going to the email website on my iphone, either.  had to wait until I got back home to use desktop pc. also, I can't find an app for the iphone that will allow me to send coin. so I'm thinking it's probably the iphone.

any suggestions on which cell phone is best for bitcoin transfers and which app?  heavens, when is someone going to invent the bitcoin phone,  !

appreciate all your help.
