RE: Steemit Crypto Academy Contest Season 1 Week 3 - Blockchain through the concepts by @wealthmary
Most people forget that blockchain is a database filled with information about the transactions that happened.
You have explained it in a good way. Do you think having a cold wallet is a good idea?
It's not really all that good, because if it is not properly protected, it will be destroyed. So I think it's safer online, where it can be easily accessed and used for quick transactions. Thanks so much for commenting on my post.
