While most coins experience a dip when Bitcoin crashes or goes down, there are a few altcoins that showcase an upward trend. These cases are rare but not non-existence
Take note of these coins, not for the future purchase but to add to your shitcoins lists. Whenever bitcoin drops there are some coins whose names have never been heard of that show 100-500% gains which means that they have been manipulated and pumped by some group. Dont get tempted to buy them because the dump is coming soon and its going to be harder than the range of the pump.
xlm and xrp are more stable than bitcoin but bitcoin will still be the choice of many people, because bitcoin has its own charm and has not been replaced, xlm and xrp are only alternatives to bitcoin, it is in my opinion
Centralized coins like ripple are a different group of assets. They may be related to crypto but putting them in comparison with bitcoin kills the original idea. Crypto was supposed to be decentralized lets keep it that way.
