I am newcomer and very interested about bitcoin. I need a wallet before I am purchase some bitcoin. What is the best and most secure bitcoin wallet?
Your suggestion is very important to me
use bitcoin core it's the best and most secure, but require a large storage at first for synching the blockchain, but then you can use the prune mode to reduce space
You have not written what you will do with Bitcoin.
If you want to buy, and sell for example in a couple of months, use poloniex or kraken.
If you want to constantly buy bitcoins, i.e. invest in them, then you need bitcoin-core
