Maajo 21, abaalmarinta Nobel Prize ee dhaqaalaha, Paul Krugman (Paul Krugman) ayaa tweeted faallo ku saabsan Bitcoin lagu daabacay New York Times, iyada oo qoraal la socda oo sheegaya in "saadaasha ay noqon doonto inaan helay emails nacayb badan, iyo" cibaado” laguma qosli karo.”Dib u eegista New York Times, Krugman wuxuu sheegay in hantida crypto sida Bitcoin ay tahay nidaamka Ponzi.

Krugman wuxuu aaminsan yahay in 12-kii sano ee laga soo bilaabo dhalashada, lacagaha loo yaqaan 'cryptocurrencies' ay ku dhawaad ​​​​wax door ah ka ciyaareen dhaqdhaqaaqyada dhaqaale ee caadiga ah.Marka kaliya ee aan maqlay in loo isticmaalay qaab lacag-bixineed, halkii ay ka ahaan lahayd wax-is-dhaafsi male-awaal ah, waxay la xiriirtay dhaqdhaqaaqyo sharci-darro ah, sida lacag-dhaqidda ama bixinta madax-furasho Seeraar oo la siiyo hackers-ka xiray.Kulamo badan oo uu la yeeshay dadka xiiseeya cryptocurrency ama blockchain, waxa uu aaminsan yahay in aanu wali maqal jawaab cad oo ku saabsan waxa dhibaatooyinka tignoolajiyada blockchain iyo cryptocurrency xalliyan.
Maxay dadku u rabaan inay lacag badan ku bixiyaan hantida u muuqata inaysan faa'iido lahayn?
Jawaabta Krugman waa in qiimaha hantidani ay sii socoto kor u kaca, sidaas darteed maalgashadayaasha hore waxay sameeyaan lacag badan, guushoodana waxay sii wadaan soo jiidashada maalgashadayaasha cusub.
Krugman waxa uu aaminsan yahay in kani uu yahay qorshe Ponzi ah, iyo nidaamka Ponzi ee mudada dheer socdaa waxa uu u baahan yahay sheeko-sheekaduna waa halka uu suuqa crypto runtii aad uga sarreeyo.Ugu horreyntii, dhiirrigeliyeyaasha crypto waxay aad ugu fiican yihiin doodaha farsamada, iyagoo isticmaalaya ereyo qarsoodi ah si ay naftooda iyo kuwa kaleba ugu qanciyaan inay "bixiyaan tignoolajiyada cusub ee kacaanka", inkasta oo blockchain uu aad u da 'weyn yahay heerarka tignoolajiyada macluumaadka oo aan weli la helin.Isticmaal kasta oo lagu qanci karo.Marka labaad, liberalku waxay ku adkaysan doonaan in lacagaha fiat ee ay soo saarto dawladdu iyada oo aan wax taageero ah oo la taaban karo ah dhicin ay burburi doonto wakhti kasta.
Si kastaba ha noqotee, Krugman wuxuu aaminsan yahay in lacagaha loo yaqaan 'cryptocurrencies' aysan daruuri ahayn inay burburaan dhawaan.Sababtoo ah xitaa dadka ka shakisan tignoolajiyada sirta ah ee isaga oo kale ah ayaa ka shakin doona cimri dhererka dahabka oo ah hanti qiimo sare leh.Ka dib oo dhan, dhibaatooyinka ay la kulmaan dahabku waxay la mid yihiin kuwa Bitcoin.Waxaa laga yaabaa inaad u malaynayso lacag, laakiin waxa ka maqan sifooyin lacag waxtar leh.
