I’m not sure it will take 6 years, I believe this is an over precaution, however, the reasons behind why it’s been done probably draws from several factors, initiating the entire coin swap at once would have seen many people immediately dumping Straks hurting the value of the coin.

Another reason is everybody realised quickly it was better to buy Sigt for the short term than mine Straks, this in turn only pumped the price of the Sigt (which is not what the Devs want) and drew miners away from Straks giving more “limelight” to Scam coin Sigt again.
