As you mentioned in your post big banks & corporations these are the institutional investors which have already entered into market and they come up openly with the Circle Trade project. They are already investing money in top cryptocurrency but are not coming openly because of lack of regulations. When these regulation problem resolves that day will be near when crypto market will reach to the sky. We are still in the early stage & there is huge potential gain if the project in which we have invested is strong and hold our investment for longer run. People who are exiting market by selling their digital assets in loss on the present scenario because of FUD & manipulation will regret later. Yes 2018 will be amazing year for those who learned about tackling market manipulation & have patience.
