I see bitcoin becoming an institutional coin in the nearest future. institutions are beginning to buy bitcoins in billions of dollars. this will automatically reduce the amount of bitcoin in circulation thereby forcing up bitcoin price.
Yes, institutional bitcoin interest affects bitcoin positively. It will push up the price and it will make it less volatile. However, as we saw in news, many institutions enlarge their crypto holdings by also adding different coins such as ETH, BTC Cash, Litecoin. When Bitcoin becomes real digital gold accepted internationally, then other coins will get the chance to perform even better. The previous interest in Bitcoin will be transformed to others.
