I just started to try out Koinly
My first impressions is that it is a good thing I started in August. For the most part it is easy to use. Many people may be greeted by the IRS questions on thier tax form and decide to try to try using it a bit late.
You will from time to time come up with some difficulty. Whatever is going on with the tronlink wallet is also going on with Koinly and it may be that Tron is trying to get you in trouble with your taxes. From a tax perspective Tron wallet could be a bad idea along with seed or at the very least you might want to keep your position small until whatever glitch they have is fixed. The Abra exchange also seems to have some trouble with it's CSV.
Overall it is a good place to tally up your coins. It really doesn't take much to get hundreds or thousands of transactions the way these companies pay out weekly or daily. Crypto back cards exc.
If you would like a twenty dollar discount you can use my referral link https://koinly.io/?via=AA1A96BA and we will both get the cash.
