I have never come across a bitcoin scam.  Ever since I started investing in Bitcoin, the number of scammers in cryptocurrency has been very low.But nowadays the number of scammers is increasing day by day.  But I lost some bitcoins due to my own mistakes.  Back in 2017 when the price of bitcoin was $12k I held some bitcoins, but later I lost some bitcoins due to a transaction to a wrong address.But the most important thing in cryptocurrency is to secure full access to your seed phrase and wallet.These accesses should never be shared with anyone, as sharing them is tantamount to giving away your bitcoins to that person.  And while adding different tokens to the wallet should be well justified because there are many scam coins in the market.
