No coinbase podes trocar bitcoin e ethereum por euros
viva
já percebi que há novas moedas electrónicas.
Sabes dizer-me as diferenças e se pensas que vão perdurar.
Achas que vão valorizar?
1 abraço
Acho que o ethereum vai valorizar a longo prazo.
Há muitas cryptocurrencies e cryptoassets, umas 700 no coinmarketcap, maioria das moedas digitais devem cair até valerem zero diria eu. Por isso pegar assim em moedas ao calhas só porque são alternativas à bitcoin mais baratas não deve resultar.
Além disso está tudo numa bolha, como há dinheiro digital por exemplo pela valorização da bitcoin e ethereum estão a aparecer muitos projectos novos baseados na blockchain da bitcoin e baseados e ethereum e está tudo num ciclo super positivo. Os riscos são os forks como o que fizeram em ethereum no ano passado e agora estão a fazer na bitcoin. Qualquer bug que possa aparecer como o que apareceu no ethereum no ano passado que rebentou com a DAO.
Eu se calhar devia vender um bocado do ethereum que comprei no ano passado, como subiu 400% nos últimos meses pode ter um crash pesado a curto prazo, e se o preço cair, o dinheiro em ethereum que está a sustentar os desenvolvimentos de projectos baseados em ethereum desaparece, e cria aquele ciclo negativo da crash das dotcoms, mas não vou vender, tenho medo de vender e perder o barco...Não tenho previsão a curto prazo, é tudo especulação, não é que existam smart contracts para justificar os quase 5 biliões que todos os ethereums juntos valem neste momento, depende de quanto é que as pessoas acreditam nisto
Já agora ficam aqui uma lista de riscos para o ethereum
https://www.reddit.com/r/ethtrader/comments/462hfk/logic_please_anyone_who_feels_eths_marketcap/d01xy12/[Technical risks]
CASPER POS is challenging and not 100% certain it will work.
Scaling & sharding is challenging and not 100% certain it will work.
Maybe despite being batshit crazy Paul Sztorc could be right that oracles are impossible
Possible long term security holes of fundamental flaws might be discovered
[Resource & cashflow risk]
Foundation has limited funds.
Key developers could be poached.
Still not seeing evidence of significant VC investment.
[Competition risks]
R3 may win financial market
Hyperledger may win IOT market
Ripple could win international settlement & remittances market.
Some anon coin may win the darknet market
Could have a million ethereum alt coins indeed consensy could themselves fork Ethereum
Bitcoin might finally sort out their politics
Rootstock & counterparty
Some new unknown coin could be a better ethereum than ethereum.
[Regulatory risks]
Goverments could clamp down on crypto exchanges
Goverments could require permissioned system or back a rival system
Goverments could clamp down on IPO or crowd shares
Goverments could clamp down on issuance of assets or create more onerous KYC requirements
[Reputational risks]
If Kraken or Polonex is the new Mt Gox
If some scam or pyramid scheme gives Dapps a bad name
If a significant number of wallets are hacked
If Ethereum community becomes as toxic as the bitcoin community
[Barriers to adoption]
It is hard to communicate what Ethereum is
Press insist on using the term 'blockchain' or 'bitcoin'
Ethereum PR sucks.
It is still hard for 'normal people' to buy Ether and securely store it.
There is not yet a killer app
Maybe nobody actually wants Dapps or even crypto currency they just want an investment opportunity
Even if there is a killer app the advantages of decentralisation are unclear
Maybe noone actually cares about decentralisation apart from nutjob bitcoiners and they only care about bitcoin
Still no major exchanges listing and hard to buy in directly from fiat
Major Chinese exchanges may never add Eth because they make all their money from mining BTC so don't want Eth to succeed.
[Risk Ethereum could succeed without Ether becoming really valuable]
Stable coins, gold & other currencies will be used for payment & wealth storage not Eth.
Eth will lose it's monopoly for buying gas
Because of competition & scaling transaction fees will fall to the cost of operation & capital.
