I am interested to know if the USD will remain strong compared to the PHP, and if it will increase in strength.
The money I earn is in USD so it benefits me when the conversion rate for USD is high. If the US Federal Reserve Bank continues to raise interest rates, I think the PHP will continue to weaken against the dollar.
That helps me a little bit since the debt I have is in PHP. It also benefits the many Filipinos who earn USD, or receive remittances from the states.
I think Steem has an advantage over Bitcoin, since the transactions in Steem are feeless, but Bitcoin transactions carry a fee.
It's hard to tell, and this is definitely not financial advice. However I have been tracking the USD to the Mexican Peso of late, and even with the NAFTA trade agreement meetings, etc. here, the Mexican Peso is trading today at about 19:1 to the $USD. I've seen peaks around 21:1, but over the past 12 months (pre-NAFTA trade) it hasn't changed more than 10%. Just remember that most world currencies are tied to the $USD, so the exchange between countries might end up in the local currency but typically the global transactions are traded in $USD. I believe you are referring to how your local currency will convert from $USD to PHP, so I think the USD is strong and will likely maintain that position. We've seen other countries (e.g. Australia) experience a downgrade in their currency value due to their close ties to China for resources.
As for Steem vs. Bitcoin, BTC is still the gold standard for crypto-currencies. The fees vary but with Segwit and Lightning Network, those fees should be reduced to almost nothing over the next 12-24 months as long as your exchange embraces these technology upgrades.
