It sounds good that most of the time you make investment in Bitcoin which is a prudent decision in view of leading its leading role in cryptocurrencies market with it distinguished features. As far Shiba Inu, whether to hold it or sell them in bullish market is ultimately your choice depending on your fincnail circumstances and risk tolerance level, however if were in your shoes, I would consider converting most of them into Bitcoin.
After I decided to keep those tokens on my local exchange, I discovered that my country's tax law requires me to pay a 30 percent tax on any capital gains and a 1 percent TDS (Tax Deduction at Source). This means that if I sell those coins, I will end up paying more in taxes than I would make from the airdrop. Therefore, I have decided to hold onto my Shiba Inu tokens until they have a USD value that is high enough to cover the taxable amount. In short, I am not going to do anything with these coins until I believe they are profitable for me after taxes.
