Hello everyone, I am interested in this question, I want to play on the exchange, sell and buy cryptocurrency in order to be in the black, I intend to do all my activities on my smartphone, what applications do I need to install and what would they be effective? Thank you very much
I think the only one you need is a 2FA app like Google Authenticator.
If you have already an operational wallet elsewhere it would be better to only install a wallet in Watch Only mode on your smartphone, that is to say without its seed/private keys, or only with imported BIP38 addresses(ie with a password) that you use once.
If you haven't already a wallet elsewhere, it's not highly recommended to store huge amounts on it (even if it's safer than a hot wallet on a PC IMO) without being extremely cautious : don't root your smartphone, don't install weird applications on it, be careful that nobody knows you have a big amount of cryptos on your smartphone, don't expose your PIN code and above all :
backup your seeds or private keys elsewhere, smartphones are easily broken and stolen.
