I might be wrong but I noticed that accounts and therefore btc limits are classified on the base of the account age.
It may sound stupid, but I think would be better to classify them on the number of trades completed, or even better both (account age and number of transactions/trades), indeed in the current situation, I can wait 30 days and then perform my “malicious” transaction.
If you’ll introduce the trades limit, in the first case (number of trades) maybe after 10 trades, I’m able to unlock the first BTC limit, this means that I’m really interested in the platform, and I prove it by keeping the client running to complete my 10 trades, while in the best scenario (age and trades) I need to wait 30 days and complete 10 transactions to be able to increase the limits.
What do you think?
