don't use your funds in Bitcoin and Ethereum, because I think investing in Bitcoin and Ethereum is a better investment than ARB, so if you want to swap your Bitcoin and Ethereum to ARB...
I believe that buying ARB will bring more profit than holding bitcoin and Ethereum. Accordingly, buying ARB now for Bitcoin, you will be able to significantly increase the amount of BTC in your wallet. Buying ARB at the price of $1 is almost the same as buying BTC five years ago at $2.5 thousand.
it's okay if you trust ARB more than Bitcoin, I personally don't really like risk, so I prefer to keep holding Bitcoin instead of inflaming Bitcoin just to buy ARB, because I believe if a bullrun occurs, then the price of Bitcoin will increase very high and of course the price of Bitcoin will create a new ATH price.
