i am prefer with gambling online because i don't need to walk away from my house and beside that i can use my time for anything thing. but sometimes i do gambling offline with my friends and its feel fun while play gambling, we can talk everything with others.

my investment strategy is first i collect btc as much as i can, from free source or i buy bitcoin. then if i only can collect like about 3-5 bitcoin, i will use 2,5 btc for trading and hold some altcoins for a while and waiting for some good price from altcoins.

in other 2,5 bitcoin, i will hold it in my wallet for long term investment, i think it will makes me a good profit in future to hold bitcoin because the rate from time to time will be up.

yes, don't forget to activate 2FA on bittrex. i think bittrex is safe and secure, i was on bittrex too beside on polo. bittrex have much of coins, i think bittrex more larger than polo.

i think its a few customer that use bitcoins, because they are really don't know about bitcoin. and if customer that you mean is us, then i would say that we use bitcoin because we know that bitcoin is like an investment, and we can make real money with bitcoin. beside that, we can use bitcoin to send and receive in short of time.

beside that, we can buy something by online with bitcoin as our payment. bitcoin can make our life simple.

my contribution to bitcoin until now is just to make buy and sell bitcoin with altcoin, because i am not sure with what i've known, so i think i will do trading for right now, maybe later if i am confident and know much of bitcoin, i will make contribution.

oh btw, i introduce bitcoin into my friends, and they are interesting with bitcoin and ask me, and i try to explain to them what i know about bitcoin, and the rest, i told them that they can search by internet or they can visit into this forum, i think they understand for what i am explaining last night.

sometime i missed the right time to sell and buy bitcoin. i think its because i don't really understand when the right time to sell and buy, because when i sell that i think its the high price, but in the 10 minutes later, the price often going up again. this is happen too when i buy bitcoin. i think its really in the bottom, but i am wrong, its going to go in under the rate when i bought. but i am not sad, i consider that is my lesson and i hope i can fix my trading way, so in next future i can make little missed rather than what i usually done.

$2,000,000 is a big money, you should careful before investing big amount. my suggestion is you can investing for only $500,000-$1,000,000 because we are not know what will happen in future.

with that $500,000-$1,000,000 you can buy hardware s9 like about 5 hardware-10 hardware, and you can build farm mining with using new PC like about 3-5 PC with each motherboard with support 4-6 vga cards to mining eth, and then if there is still money left over, you can buy bitcoin and hold it for half, and for the other half, you can use for trading.

i hope you can get success with your investment.

What will be the monthly revenue?
for 1 s9 a day = 0.285 BTC
monthly = 0.285 BTC x 30 = 8.55 btc
if you have 10 of s9 = 8.55 btc x 10 = 85.5 btc

What will be the yearly revenue?
for yearly = 85.5 btc x 12 = 1026 btc

1026 btc x $650 = $666,900 in one year

Cost of maintenance?
$4000 x 12 month = $48,000

that is just for s9, i am not understand how to calculate for mining etch, maybe its like the same as calculating for bitcoin. you can search in search engine and read more to know the calculate.

i only try to calculate with todays condition, i don't know what will happen in next one year, but with my calculate, you can make your ownself calculating and you can make your decision.

i am sorry if my calculating its wrong because i don't mining with any hardware, its too expensive for me, i only try to make sample for you and i hope you can do the calculation with yourself.

i will withdraw 10 bitcoin and i will hold the other and maybe i will use 3 bitcoin for trying to trading, because i know that trading can help us to grow our bitcoin and we can have other altcoins with buying some amount. i wonder, when i can have 21 bitcoin? hmm i was curious about this, maybe let the time will give the answer.

i know bitcoin is about 6 months until 1 years ago, if i am not wrong, but i am not yet know the details of bitcoin. and maybe we are here know about bitcoin in long time ago and we don't take too much attention on bitcoin, so in nowadays, we are regret it that why we are not use bitcoin since we know bitcoin. this is happen to me for sometime but now i am ready with bitcoin and i want to make money with bitcoin.

i believe that bitcoin have a good assets in future. because i see for todays, many people is interesting with bitcoin and they really want to know more about bitcoin. and i think bitcoin will be survive in future. the more people know and used bitcoin, the more grow bitcoin than we all know already.

i am not yet sending my bitcoin into everywhere beside hold it into my wallet except for make withdraw to my friends  and i prefer to receive bitcoin rather than sending bitcoin 

i am afraid that there is no other way you can do, because what i've read, if one transaction is made and its show in the blockchain, then its can not to be undo. but i don't know if there is another way to recover your bitcoin.

i love bitcoin since i can make my first withdrawal in about $30, i know its not much but its really makes me smile and i can tell my family that i can make money with bitcoin. i don't know about the blockchain technology, the only thing i care is how i can make money while i am online. this is my main purpose and i really like that bitcoin is help me to do this.

agree with this so we still have 1 bitcoin in our wallet for in case something is happen to us. i learn about trading that could help us to make our bitcoin grow and i am trying to do this. i hope that i can get profit from trading too like others.

i read on other thread that there is porn website is accepting bitcoin as payment and maybe i am prefer to see video and live show  i like the natural and watch the girls doing their activities.

i think i will just hold my bitcoin in my wallet, because right now i see on poloniex and other market, the rate of bitcoin will get down and i am not sure until where its going down. so for me, better to hold it for a while and waiting next movement of the price.

i think and if i am not wrong in remember, i bought bitcoin in 3 months ago but i am not sure. i only bought about $15 in my friends because he is selling and buying bitcoin. and until now, i think i am buying bitcoin is only for 1 times.

i only know on my mycelium wallet, there is an option for slow, slower, normal, fast transaction fee and i always choose normal for transaction and sometimes if i am in hurry, i choose fast transaction fee. but i don't how to find out the optimal network fee on market exchanger, because on every market exchanger have different fee.

what i am doing is get relax for a while with my glass of coffee and watching some movie, beside that i make a chat with my group on WA and BBM. i don't take too much thinking how long confirmations will be finished, because when i see there is any transaction i receive in my wallet, and its just show 0 confirmations, i know it will finished by itself, so better i used my time for doing other activities.

for offline wallet, i used bitcoin core and multybit, and so far its works good for me. but for bitcoin core, i am a little bit desperate when waiting for syncronization.

but for the other wallet, i use mycelium and its a good choice for me.
