To be honest pag security ang biggest factor natin(which is tama naman), we should use hardware wallets instead of leaving funds on coins.ph, abra, or any other fiat<->crypto service.
Magkano ba hardware wallets sa ngayon? 6k? 7k? sa totoo lang 'di naman lahat sa atin would be able to invest in such item for our coin's security. Kaya no choice karamihan sa'ting mga pinoy but to leave their funds to these services.
Personally, I haven't really tried abra, but by the looks of it, mas maganda parin coins.ph kasi mas marami itong options regarding cash-out and cash-ins. Sana lang talaga they would update their system and give the control over the private keys to their users instead of them holding it for us.
