As for me, the most reliable coin for long-term storage is bitcoin. I was convinced of this in 2018. Now most of my capital is invested in bitcoin.
Your choice is very appropriate to entrust bitcoin as a place of investment. no need to hesitate with bitcoin because bitcoin has a high selling value and many people like it now so that bitcoin will be increasingly sought and will increase its value. my view of the best place of investment is two, namely BTC and ETH.
