Block chain is a store of value. Even if your coin is not currently improving it is still a store of value. Sum coins being more volitile than others. It ur research on what coin to invest. Bitcoin is the first digital gold used as a store of value. Then there are alts who might be less volitile.
Don't quite understand what value you mean when talking about bitcoin and alts... The value that is being created by the fact that many people are thinking that crypto is a valuable thing? This value?)
