as for me the safest way to buy bitcoin is to buy it at well-known and trustful exchange. you will save your money and your nerves.
Exchange sites are good options in purchasing bitcoins, I think there are even
apps that make bank deposits and remittance centers as convenient methods
to buy bitcoins in a way or process, I think coins.ph is an excellent example of
such a method, my friend in the Philippines has been going on about it, I believe
it even has it's own BTC and ETH address and a convenient converter. I've also
tried making or having the assistance of someone more familiar and already has
accounts with exchange sites in buying bitcoins back when I was still new to all
of this, though I suggest that it would be someone honest, trustworthy and
someone you know, to avoid discrepancies on the process.
