For me i think if you had fully control with your private keys or seeds you can use blockchain but i am not guarantee that you can safely save your bitcoin into blockchain.. or i think much better to save your bitcoins in paper wallet instead if you really want your bitcoin to be save safety..
Much more recommended wallet i think you can use electrum that i think much safety of our bitcoins.

Mostly investment site are almost all are scam so don't start a business  like investment site..
 I just notice your account was recently change the password that i think there is suspicious about that account.
I don't believe if you are the owner of that account except if you can sign a message of the old stake address or quoted address.

I was thinking why he can't withdraw and i think sending the coins is enough as your withdrawal method and transferring your funds from coinbase to bitcoincore
I think he is talking about transferring or sending because withdrawing from coinbase to bitcoincore we can considering as sending bitcoin to bitcoin core..

Always keep in eye and monitor after release it in the market if you invest in care4me it can gives you a good opportunity to make a good profit.
And this project is really had a good plan and good development.

Hope that Litecoin will be increase the same as your speculation this following year.. but i don't believe in Dash.. and i think the price will be down instead of increase value
Litecoin much better and a little bit increase in ethereum overall i think fine . but anyway good speculation..

There is no investment site that i think can give as a free profit or earnings.. everything here in online needs to work in order to earn bitcoin..
If you want to earn bitcoin you have some skills or do some bounty even here you can see some bounty and earn altcoin or bitcoin just doing the bounty this is more easy and safe to earn unlike you are investing and you will never get your investment back..

I think they are just curious about bitcoin and the amount they invest like other said is just a small amount that i think its under testing if they can make a large amount of profit since they already bought 2 bitcoin more or less they can make a large profit if the price of bitcoin will increase more after this august  if they discover that there is a good profit in holding bitcoin expect that they can invest more in bitcoin that can also affected the price to go more high or it can be worst result because he can control the value of bitcoin and gaining this man can make more profit.. just lets hope that it can help to increase the value of bitcoin or else he is trying to manipulate the price of bitcoin.

As i can seen its fake i couldn't seen any transaction made in the address what he posted by op i just tried to  import it into wallet but you can see clean no transaction made its totally clean but when checking it in blockchain you can seen that there is $257 transaction made but inside no transaction history.. its not like my address you have a own history.. Beware guys..

I think you can earn in litecoin depends what is the speed of your mining tool better to check this site https://www.cryptocompare.com/mining/calculator/ltc

And you can see almost other altcoin there for calculation if what altcoin is the best to mine and more profitable these days..
Litecoin was also good to invest but its really expensive hardware but you can be still make a good profit if you go to buy more high speed miner that can mine fast and earn more profit..
Here in my place or country if i have a miner i can make more profit here because we are not paying electricity here.. Hope that i can make my own miner too to mine altcoin..

This is what i am looking for many months but i was checked the site i though you can only put the specs of the gpu and you can see your hash rate speed..
Hoping to see a tools online that you can only put the MHZ, GB and overclock maximum and minimum that can give you total hash rate per second with that gpu..
But anyway it can be still help me to have idea.. ..

I think your the only one can help your self for making new crypto currency because other people here are just always afraid of scam and they are always choosing a trusted people than a newbie posting a thread the same as other posted here in altcoin discussion ..
Many scam coin are always release in trading site that i think only developers are getting benefits for their project..

If ever you need a campaign i can promote this project with my knowledge of syndication and ranking it in google and any search engine you can hire me if you need.

Ethereum honestly its just for gambling and trading purposes unlike bitcoin that its world wide use as you can see more country locally are accepting bitcoin as payment and some country are legalized bitcoin like in japan..
Or many site treat bitcoin as payment option.. Bitcoin is more usable online than ethereum as you can see the difference from them . ethereum still be an altcoin the codes inside is the same codes what is use in bitcoin the difference for that is the addition feature added in ethereum ..

This is new great promising coin and its awesome project and i think more people will support this.. When this token sale distributed ends?
I was join in their bounty and hoping if ever its available to send i would plan to invest with my bitcoin in the future. for now don't have extra budget but i can do some bounty about this project to get few carecoins once the distribution is done.

Never tried their cloud mining feature and this is my first time to heard that they had the cloud mining option i thought they are only giving a software to mine coins to use gpu or cpu mining..
If they are offering cloud mining service i don't know if they are be still legit or not..  since they are old miner software where you can mine in your own pc or mining rig..

The fact there is no other long term investment gambling is just for gambling activity only and not good idea to invest there for a long term anytime you can be lose all of your investment.. the only thing that i know investment that good investment for a long time is investing in bitcoin and holding them for a long time that i can say its a good investment because the price of bitcoin increasing fast day by day..

Honestly its not safe to use  jaxx  wallet but if he wants temporary he can use it.. for me for safety wallet you can use ledger nano s that you can use offline wallet for multiple cryptocurrency..
This is more safe that other wallet online.. the best thing there you can use the wallet offline and you can backup all private keys unlike the other wallet..

For me the best to use is 2fa never had any problem or hack activity to my account or even they are trying to login they cant login because it will be ask first for autheticator and i use google authenticator..
That much more secured but you should always back up your authenticator once your app is corrupted or your computer crashed.
there are site that actually you can receive pin its also secured i think once you email is always unique in password..

Thanks to let me know where i can make ethereum wallet i have both private key and the key store and i think its enough to save and receive my bonus in ethereum after end of the campaign...

Hi i would like to ask what the actually use of ethereum address when register i check the spreadsheet and check the ethereum address 1 by 1 but there are no transaction receive when checking in ethereum blockchain explorer.
I would like to join but i only have bitcoin address. Do i still have a chance to join to this campaign?

In my case if i win a jackpot i play continue with small amount just to increase more but if the small amount lose well i stop and go to treat my family or friends and buy thing that i think i can use for daily use..
Because this way i can feel that i win a jackpot than you are just win and gamble them back again or save it for a long time but you are still gamble it will be still useless.
