the only way for bitcoin price to truly rise is when its adoption grows, nothing else works. any other weird thing you try may work short term (like how altcoin pump and dumps are) but in the long run these things can not be sustained and will fail and all the gains would vanish.
this is actually why bitcoin price continues to rise even after 10 years of rising!
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)
- exchange print tusd and usdt (loan bank )
to be honest these two don't even make sense, specially the second one since it sounds like you want fake money be printed and injected in bitcoin to raise its price but you forget that it can crash just as easily and you also forget a more important thing that people aren't going to use these tokens to buy bitcoin, they will continue using their fiat to buy bitcoin.
- 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.
you can't put this kind of silly restrictions on the market. it needs to remain a free market. besides the coins like mtgox coins need to enter circulating as fast and easy as possible so that we can have a better distribution of bitcoin.
ps. mtgox had nothing to do with the 2018 drop!
