I think that the prices of bitcoin need a strategy from investors and traders & devlopers & companie

for example: - like mid 2017 When top exchanges imposed very strong restrictions to all deposit.
- creat special box loan fund (1 - 10 percent profit after 6 month & 0.01 percent profit after 1 month in top and trust exchange like binance , bitfinex , bittrex ) and that will encourage investor for holding their bitcoin with profit(  imagine if people invest about 1000000 btc for 6 moth and they can't desactive investement before 6 month.that can make price in stability and  bitcoin will gain time to 2020 and circulation of bitcoin will drop little)
- max sell in exchange is 1 bitcoin per day , without multiple acount (this is good way!) , there is no max buy
-dont allow mtgox and whale to sell their bitcoin in exchange.
- exchange print tusd and usdt (loan bank )
