Seems a really FOMO experience
That's bad news for you mate. For sure in your country, they are very strict when it comes to Bitcoin or any cryptocurrency transactions.
It's fine, maybe you can just buy some stablecoin and wait for some pullback or dip so you can properly positioned.
During FOMO times, it is not wisely to bu even stable coin because the rate of stable coin to a fiat currency usually will be higher, more expensive than normal rate.
Better times to buy stable coin is when there is no big rise or crash on the market, when the market is boring, you will have better rate of stable coin vs fiat currency to buy stable coin and wait for opportunities to buy discount Bitcoin when FOMO effects gone and panic appears on the market.
when it comes to buy deep the fear of falling further always appears, so the best strategy will always be DCA, regardless of the value. Buy a little a week and make peace with yourself. Don't feel guilty about anything at all, you did what was supposed to be done at the time.
DCA is a very good strategy for investment as it will help to eliminate or reduce fear and other emotional effects. A more important contribution from DCA is it can help you to accumulate bitcoin and increase total value of your investment with time. You even don't realize how much you spend for DCA and what value of your portfolio is after a while. Some months, when you look back and watch your portfolio, you will be surprised with what you already spent for DCA.
