Already philippines have regulations for using cryptos?
If its still in the uncertain phase,then using bitcoin for buying properties without regulations may bring some difficulties later.
The said properties was not own by the Government, it is a private properties by rich people, and buying it using Bitcoin and Litecoin is the same as buying it with fiat, it will just bring some difficulties to whoever buys that if the needed legal documents are not legit, the Government might take the property in that case, but this is all good in my jurisdiction since the owners are crpytocurrency enthusiasts.
It is a nice move for them because they don't need the money that much (since they are rich) and holding bitcoin 'till its price skyrocket again is no problem for them at all.
