It really depends on the exchange rates of złoty in the future, because it's been becoming always stronger for the last few years (not long ago 1 USD = 3 zł, now it's only 2.20 zł, a British pound from about 6.50-7 zł has fallen down to 4.20 zł, euro is relatively strong, but it also lost to Polish złoty). I'm not expert (or even interested) in exchange rates, so I can't say you what the trends will be in the next 12-24 months.
btw, if you put 60,000 zł in a savings account (for example in ING Bank Śląski), you'd get about 185 zł intersts each month (equal to about 84 USD at current rates). And you will be allowed to take out any amount of your money
once a month without losing the interests. So it's about 3.75% a year, those 14% interest in Turkey look much more attractive, but you need to include the inflation in your calculations, if Turkey has a low inflation (3-4%), then it's probably a good idea.
But I'm afraid it's not tha case, here are Polish exchange rates for the Turkish Lira from this year (average values):
lira tureckaJan, 1 TRY = 2,0892
Feb, 1 TRY = 2,0344
Mar, 1 TRY = 1,8378
Apr, 1 TRY = 1,6784
So it's losing its value, it seems. It has lost 20% since the beginning of the year, so your 14% interests from a Turkish bank would mean -6% (minus 6) in Poland,
