Tungsten

A: Ob peb lub lis piam dhau los, tungsten cubes (tungsten cubes) tau dhau los ua neeg nyiam nyob hauv lub ntiaj teb cryptocurrency, ua rau nws nyuaj rau cov tib neeg kom nkag siab tias yog vim li cas lub voos xwmfab me me tuaj yeem ua rau cov neeg nyiam tshaj plaws ntawm cryptocurrency. Dab tsi yog lub zog khawv koob ntawm nws?
Cryptocurrency enthusiasts uas tuav tungsten cubes txhua tus muaj kev xav zoo ib yam, uas yog, lawv xav tias lub ntiaj teb no yog tiag tiag, tsis zoo li Bitcoin, uas tsuas yog nthuav tawm nyob rau hauv daim ntawv ntawm tus lej thiab tsis tuaj yeem tso cai rau nws cov neeg tuav kom hnov ​​​​nws lub neej tiag tiag, thiab kov nws.
Nws tau hais tias feem ntau cov tub luam cryptocurrency uas tsis tuav tungsten cubes tam sim no xav tias ntshai heev li yog tias lawv tau plam qhov xwm txheej loj. Nws yog FOMO phenomenon, uas yog, "Ntshai ntawm ploj mus" (hu ua "Fear of Missing Out"). FOMO "hais tshwj xeeb rau kev ntxhov siab ntawm ib txwm txhawj xeeb txog kev poob lossis ploj ntawm ib yam dab tsi, tseem hu ua "tus neeg sab nrauv qhov teeb meem").
Torkel Rogstad, tus kws tshaj lij software ntawm cov nyiaj txiag digital platform Arcane Crypto, tau tshaj tawm cov tweet ntsig txog Twitter. Nws hais tias: "Nws mob heev rau tos txog qhov tuaj txog ntawm tungsten blocks." Qhov no ua pov thawj FOMO ntawm Tungsten Cube, lossis FOMO WC (FOMO ntawm Tungsten Cube) ntawm cov neeg uas tsis muaj lub cev khoom hauv tes.
Muaj kev cuam tshuam los ntawm cov xov xwm uas cov neeg nyiam cryptocurrency tau xav txog nrog tungsten cubes, cov tub lag luam cryptocurrency thiab txawm tias cov neeg zoo tib yam uas tsis tuav nws kuj tau tso kev txiav txim los yuav ntawm cov platforms kom sai li sai tau, ua rau muaj kev xav tau ntau ntxiv rau tungsten cubes.
Lub tungsten lub voos xwmfab yog lub voos xwmfab uas muaj cov hlau tsis muaj zog tungsten, xws li cov tungsten ntshiab, tungsten-tooj ​​liab alloy thaiv, tungsten-nickel-hlau alloy block, thiab tungsten-silver alloy block, thiab lwm yam, feem ntau yog siv los ua cov ntawv hnyav. Paperweights yog cov khoom siv los nias cov ntawv thaum sau thiab kos duab. Paperweights ua los ntawm cov khoom tungsten muaj qhov me me, qhov hnyav dua, hnav tsis kam, corrosion kuj, oxidation tsis kam, siab kub tsis kam, tsis kam rau deformation thiab fading, thiab lwm yam nta, yog li nws khaws nws cov qub tsos txawm tias nws siv ntau xyoo. .
Dab tsi yog qhov muaj hmoo tshaj yog tias tungsten alloy paperweight polished nrog cov cuab yeej pob zeb diamond muaj qhov zoo nkauj dua thiab zoo dua. Nyob rau tib lub sijhawm, kev kos duab lossis cov qauv tuaj yeem nqa tawm ntawm nws qhov chaw, yog li nws tuaj yeem siv los ua khoom plig lossis khoom plig rau phooj ywg.
Hais txog cov nqi tsim khoom, tus nqi ntawm tungsten cubes tsis yog tsuas yog cuam tshuam nrog cov ntsiab lus tungsten thiab cov nyiaj ntawm lwm cov khoom siv pabcuam tab sis kuj cuam tshuam los ntawm nws qhov loj. Feem ntau, thaum tus nqi ntawm cov khoom siv raw yog nyob rau hauv ib qho chaw, qhov loj ntawm lub square, tus nqi ntau dua, vim hais tias cov squares loj yog qhov nyuaj rau txheej txheem thiab tsis tshua muaj siab ua rau sandwiching, tawg, deformation, los yog tawg.
