If it's too big of a number for you, then better remake / recover those records. Luckily you have a permanent record called the blockchain.
Again, very rough. You need concrete numbers once you do actual trading, because in the U.S. you are required to make estimated tax payments. The actual numbers can, for example, vary wildly from nearly 0% to upwards of 50%.
* These are based on a typical 15% federal tax on long-term gains and 5% for state taxes; or 35% being a comfortable average for most people's effective tax rate in the U.S. for short term gains. The 50% tax rate is approached when you have largish gains, toward $1 mil or so, and live in expensive states like New York or California.
Calculating your profits (and loses) is what these sites generally do -- that is usually the hard part, especially if you have a lot of transactions. Not to mention, the way that you calculate that differs by jurisdiction. Loses are just as important since they can have a significant benefit to the taxes you owe. I use bitcoin.tax and then export the data for my accountant to fit into the rest of my tax return.
I also don't steal books from the library, even though I'm pretty sure I could get away with it.
Pay unto Caesar and all that. But avoiding taxes through financial privacy is not equivalent to stealing. And certainly don't imply that an empire's aggressive wars are in any way akin to local community services!
I don't think stealing books from library at any kind of scale approaching the value of tax evasion is so easy to get away with.
Pay your taxes!
I only ever played with small amounts for fun, and in the long term, I took losses. But it's very difficult for me to compile all my trades for tax reasons. I set up automated trading on half a dozen different exchanges (some of which no longer exist) using half-baked python scripts with no logs. How on earth do I compile a Form 8453 showing all of those thousands of trades? I could spend months tracking down all the public keys I used and use blockchain explorers to compile a list of transactions... but I would not describe this as easy
the best thing about bubbles getting larger is that more people with more personalities and expertise are aware of what these things are. A judge wouldn't rubber stamp a subpoena on such basic and flawed logic, a treasury secretary wouldn't trust their employee with as shoddy an analysis, influential senators wouldn't believe it as their own altcoin trades wouldn't be counted. speculation drives innovation.
Since we've just had our Happy New Tax Year, other UK readers might be interested in this Reddit thread, if only because of the tax-related links: https://www.reddit.com/r/BitcoinUK/comments/ba8d89/tax_threa...
pragmatic answer: only if you interacted enough with the US financial system that the IRS might catch you.
You can short established coins like BTC and ETH.
There are also so called "flip seasons" where you throw money at random small cap altcoins and flip them 30-200% higher over the course of a month. These happen whenever BTC settles down and consolidates before plunging to news lows.
You can, but it's hard to find reputable vendors that offer this that aren't bucketshop scams.
