What, do you think, the governments of different countries will do next to manipulate Bitcoin? Will it be to drive the price up or down?
In my opinion manipulation on bitcoin price levels already happening like some governments are secretly buying bitcoins and to buy cheaper they might be manipulating bitcoin markets. If more governments are involving into bitcoin markets then we can obviously expect prices to go up but if one or tow countries try to grab cheaper bitcoin then they may go for manipulating prices to fish for cheaper. There are whales hence we can expect sharp down fall at anytime before we start travelling to moon and stars.
The problem with this theory is that it is hard to prove if governments specially US is really buying and hedging bitcoin. For now we don't have solid proof that indeed US is on so called manipulation.
When more government start participating into bitcoin or different busies level which means we even considering such participation/suggestion as manipulation, bitcoin prices will definitely skyrocket. Government manipulation will be good whereas individual or corporate' manipulation should be avoided or need to approach them with more care.
Bitcoin price skyrocket because of simply law of supply and demand. If retail and institutional money will flow then it will really go up. But government admitting that they are into bitcoin are rare, maybe except for those countries who are trying to circumvent any trade embargo like North Korea.
