Thank you betong! In fact I have some money, I can afford to invest about 100 USD at the moment. In my imagination POS wallet is a digital wallet, where I keep my bitcoins. It is sth like an IBAN in the bank. If this is correct - I already have my BTC pos wallet in blockchain with the specific address. What can I do with it? And second question - what mean lending bots? As I know a bot is sth like a robot? Could you explain me and adviceme what to do for your 2 suggestions - going to POS wallets and lending bots. I am a real beginner in mining and I am not very familiar with the terminology. Thank you in advance! Great weekend!
