I am not sure what you mean because 'BTC tips' keeps giving me a different result on Google. 

If you want to learn more about Bitcoin, better attend some professional courses. I don't think that asking about this on some forums is a great idea. All I can say that it is worth investing in this cryptocurrency. It has a lot of advantages. Most of all, I like that you can stay anonymous while making transactions. The bitcoin tumbler can help you with this. It uses unique code to make sure you do not get the same coins in other transactions. This is great because no one can follow your transactions or from where your BTC came from.

There are a lot of crypto transactions that have gone well over the years. There are just a lot of it that is still relevant up to this dayy. For reference : https://learncrypto.com/knowledge-base/how-to-use-crypto/exploring-crypto-transactions
