U.S. Democratic presidential candidate Robert F. Kennedy Jr. unveiled a plan to exempt bitcoin (BTC) from capital gains tax when it is converted into U.S. dollars and to begin to back the greenback with "real finite assets" such as gold, silver, platinum and bitcoin, Coindesk reports. 

"Backing dollars and U.S. debt obligations with hard assets could help restore strength back to the dollar, rein in inflation and usher in a new era of American financial stability, peace and prosperity," said Kennedy. He would start the process, he said, "very, very small, perhaps 1% of issued T-bills" would be backed by hard currencies like gold, silver platinum or bitcoin.
