I have been hodl'ing one BTC in a cold wallet.  Plan was to keep this indefinitely as longterm investment.  I have some BNB (Binance coin) and have great faith in the coin.  Considering to sell my BTC to pick up more BNB.  Theory:

As I write this:

BTC at $6680 USD
BNB at $13.40 USD

If I hold BTC and it goes up to the prior high of $19,500 USD, then I have $12,820 USD.
If I sell BTC for 500 BNB and it goes up to the prior high of $24.66 USD then I have $12,330 USD.

But, say BNB exceeds the high (Which I feel is very possible because they are the best exchange out there and keep doing new things) and hits $50 USD a coin (Or more), I am at $25,000 USD.  I know Bitcoin can also exceed the prior high, but I feel if it happens it will be later (Maybe 2019, 2020?). 

What do you all think?
