no coins can replace bitcoin . bitcoin's transfer fees are now relatively high and the transfer time is relatively long . however , bitcoin technology has been evolving . the technical team will soon resolve these issues
I believe no other coins can replace on bitcoins expensively and its popularity. Lately, most of the coins are declining its value while bitcoin has start to pumping up. Lets just be hopeful that bitcoin will continue to grow and be persistent. And I assure you its worthy to invest in this asset where we can gain more profits and benefits as long as we have a great patience on holding it.
