please PM me your CV

do you have any experience in building startup?

//module required

all binance and eth giveaway in twitter and live youtube seem a scam.
they tried to get money from people who send some money at their address.
i never hear about "real " giveaway in twitter and live youtube just by sending ethereum

seem this is just a bitmex doing this, seem bitmex just want to get profit from people who get margin call and lost his money in leverage

Do you have tried Huobi margin trading ? i think margin trading is better than Leverage model trade.
in margin trade, the margin call 130%, and its more safe than leverage trade, where you can lost easily just by flash pump or flash dump.
of course stop loss and stop profit is the best way to minimize your loss, dont forget to use it in Margin trade or leverage trade.

current price of minerium v1 is 148 satosi or $0.013810 so in thats price we will receive arround  23171 ?
in fact the 24 Volume transaction only : 34 008.47875389 MNE or 0.05038410 BTC , i have  joined again and use some address, hope the price can rising like XRB

just claim some minute ago, but i ca't understand your claim, you said free $350 per address, wheres we know the value if the coin not yet released, not yet listing in any exchange?
or the reward is depending on mine v1 rate?

is this first time you using mixer system? yu will receive your coin after all transaction confirmed


i just watching this competition, will join in last day if the participant only a few people

Im linux user, I have moved from Windows to Linux for 3 months, and now im loove with linux, everything is smooth and im never see any dangerous activity, if you love decentralization, and you love crypto, also doing some finance activity better you use linux, in my office all people using linux too. its more secure than windows even you using paid antivirus

sorry for all my invalid submit above
this is the valid submit
